The coordination nanosheets (CONASHs) are emerging as a new class of functional two-dimensional materials, which are one of the most active research areas of chem. and physics in this decade. Despite the success of various structural and functional CONASHs, the development of a new mol. structure to discover alluring functional CONASHs remains challenging. Herein, we report successful preparation of two novel CONASHs (NBP1 and NBP2) through coordination between one of the unexplored mol. frameworks of bis(2,2′-bipyridine)-based ligands (BP1 and BP2) and Fe2+ ions. Using a liquid-liquid interface as a platform, large-scale thin films of multilayer CONASHs have been prepared without any support, which can be deposited onto any desired substrate. Detailed characterization of the CONASHs using various microscopic and spectroscopic techniques reveals homogeneous and flat morphol. of nanometer thickness with the quant. formation of tris(2,2′-bipyridine)-Fe2+ complex motifs in the nanosheet frameworks. The color of the films has been tuned from blue to magenta by the suitable mol. design of the ligands. Owing to the insolubility of the CONASH films in any solvent and the presence of redox-active Fe2+, we explore the functionality of these nanostructured thin films deposited on indium tin oxide as electrochromic materials. The CONASHs exhibit color-to-colorless and color-to-color electrochromic transitions with attractive response times, switching stabilities, and coloration efficiencies. Finally, we demonstrate solid-state electrochromic devices of the CONASHs operated at a potential range of +2.5 to -2.5 V, which are electrochem. stable for several switching cycles, suggesting that these CONASHs are potential electrochromic materials for next-generation display applications. In the part of experimental materials, we found many familiar compounds, such as 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Computed Properties of C12H12N2)

《Peptide-Conjugated Long-Lived Theranostic Imaging for Targeting GRPr in Cancer and Immune Cells》 was written by Wang, Wanhe; Wu, Ke-Jia; Vellaisamy, Kasipandi; Leung, Chung-Hang; Ma, Dik-Lung. Category: pyridine-derivatives And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

Gastrin-releasing peptide receptor (GRPr) plays proliferative and inflammatory roles in living systems. Here, the authors report a highly selective GRPr antagonist (JMV594)-tethered iridium(III) complex for probing GRPr in living cancer cells and immune cells. This probe exhibited desirable photophys. properties and also displayed negligible cytotoxicity, overcoming the inherent toxicity of the iridium(III) complex. Its long emission lifetime enabled its luminescence signal to be readily distinguished from the interfering fluorescence of organic dyes by using a time-resolved technique. This probe selectively visualized living cancer cells via specific binding to GRPr, while it also modulated the function of GRPr on TNF-α secretion in immune cells. To the authors′ knowledge, this is the first peptide-conjugated iridium(III) complex developed as a GRPr bioimaging probe and modulator of GRPr activity. This theranostic agent shows great potential at unmasking the diverse roles of GRPr in living systems. The results came from multiple reactions, including the reaction of 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Category: pyridine-derivatives)

Formula: C12H12N2In 2019 ,《Optimisation of octahedral iron(II) and cobalt(II) spin-crossover metal complex for thermoelectric application》 appeared in Materials Chemistry and Physics. The author of the article were Ibrahim, N. M. J. N.; Said, S. M.; Hasnan, M. M. I. M.; Sabri, M. F. M.; Abdullah, N.; Mainal, A.; Salleh, M. F. M.; Izam, T. F. T. M. N.. The article conveys some information:

Four spin-crossover (SCO) complexes with general formulas, [M2(CH3COO)4(L)2] and [M(L)3](BF4)2, where M = Fe(II) and Co(II), containing extended π-conjugated bipyridyl ligand and N3-Schiff bases appended with linear C16 carbon chains at the N atoms were successfully synthesized and characterized. Correlation of its structural properties to thermoelec. behavior was studied: (1)structure of complexes, (2)choice of metal center and (3)choice of counterions. The structure of the mol., i.e. mol. vs. ionic has the largest impact on the SCO behavior. The mol. complexes with higher percentage of high-spin (73.4% HS for Fe-dinuc and 78% HS for Co-dinuc) produced the highest Seebeck values in mV K-1 (-0.57 ± 0.01 for Fe-dinuc and -0.58 ± 0.01 for Co-dinuc) due to the weaker metal-to-ligand bonds resulting in the increase mobility of the I- during agglomeration formed, thus increased the entropy in the solution Addnl., choice of metal center also was a factor to determine the magnitude of Seebeck performance due to the spin state transition during electron transfer. For counterion effect, it has the effect of determining the sign of the Seebeck value where I- is easier to oxidize/reduce process compared to CH3COO- and BF4- due to lower redox potential. These findings will assist in a systematic mol. design pathway for high potential SCO complexes for thermoelec. applications. In addition to this study using 4,4′-Dimethyl-2,2′-bipyridine, there are many other studies that have used 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Formula: C12H12N2) was used in this study.

The author of the article were Balakrishnan, Gopalakrishnan; Rajendran, Thangamuthu; Murugan, Krishnan Senthil; Ganesan, Muniyandi; Sivasubramanian, Veluchamy Kamaraj; Rajagopal, Seenivasan. The article conveys some information:

Synthesis of the four rhenium(I) diimine surfactant complexes of the type fac-[Re(CO)3 (α-diimine){4-C11py}] CF3SO31a-1d (α-diimine = 2,2′-bipyridine) (a), 4,4′-di-methyl-2,2′-bipyridine (b), 4,4′-di-tert-butyl-2,2′-bipyridine (c) 4,4′-dinonyl-2,2′-bipyridine (d) and 4-C11py = (py-4-(CH2)10CH3) has been reported. In vitro protein (HSA and BSA) binding studies confirmed the binding affinity of the complexes toward the drug binding sites of subdomain IIA and IIIA, confirmed by spectral studies and mol. docking. The steady-state and time-resolved fluorescence spectra confirm that the static quenching, due to complex formation, is the dominant mechanism for fluorescence quenching. Mol. docking studies prove that hydrophobic interaction makes a predominant contribution even though hydrogen bonding does exist, and hence 1b, 1c and 1d exhibit stronger binding relative to 1a. The synchronous fluorescence and CD spectral studies show that these Re(I) complexes can induce conformational changes in the proteins. Finally, the distance, r, between donor (proteins) and acceptor (Re (I) complexes) obtained through FRET study is in the range 4.5-5.2 nm.

In 2019,Journal of Coordination Chemistry included an article by Momeni, Badri Zaman; Fathi, Nastaran; Janczak, Jan; Shahsavari, Zahra. Application In Synthesis of 4,4′-Dimethyl-2,2′-bipyridine. The article was titled 《Dihaloplatinum(II) complexes having diimine ligands: crystal structure, thermal properties, cytotoxicity effects against breast cancer cells and application as a precursor towards nanoparticles》. The information in the text is summarized as follows:

The reaction of potassium tetrachloroplatinate(II) with di-Me sulfide and a mixture of HBr/KBr affords trans-[PtBr2(SMe2)2]; [PtBr2(Me2bpy)] (Me2bpy = 4,4′-dimethyl-2,2′-bipyridine) was prepared from the reaction of trans-[PtBr2(SMe2)2] with Me2bpy. The crystal structure of the yellow form of [PtBr2(bu2bpy)] (bu2bpy = 4,4′-di-tert-butyl-2,2′-bipyridine) was determined by x-ray crystallog. The x-ray single-crystal structure determination of complex [PtBr2(bu2bpy)] reveals that the platinum adopts a square planar geometry with a twofold axis through the platinum atoms. Thermal properties of the related series of diimine platinum(II) complexes [PtX2(bu2bpy)] (X = Cl, Br, I) reveal that the thermal stabilities increase [PtI2(bu2bpy)] < [PtCl2(bu2bpy)] < [PtBr2(bu2bpy)]. [PtBr2(bpy)] (bpy = 2,2'-bipyridine), [PtBr2(Me2bpy)] and [PtX2(bu2bpy)] (X = Cl, Br, I) were studied by MTT assay against two human breast cancer cell lines of MCF-7 and MDA-MB-468 with [PtCl2(bu2bpy)] having a higher cytotoxic effect towards both cancer cell lines, which shows the significant role of the halide and diimine ligand. Semi-spherical Pt(0) nanoparticles (NPCs) were prepared by the simple calcination of [PtX2(bu2bpy)] (X = Cl, Br, I) at 800° in air.

The use of nanovectors in several medicinal treatments has reached a great importance in the last decade. Some drugs need to be protected to increase their lifetimes in the blood flow, to avoid degradation, to be delivered into target cells or to decrease their side effects. The goal of this work was to design and prepare nanovectors formed by novel surfactants derived from the [Ru(bpy)3]2+ complex. These amphiphilic mols. are assembled to form metallomicelles which can act as pharmaceutical agents and, at the same time, as nanovectors for several drugs. TEM images showed a structural transition from spherical to elongated micelles when the surfactant concentration increased. Fluorescence microscopy confirmed the internalization of these metallomicelles into diverse cell lines and cytotoxicity assays demonstrated specificity for some human cancer cells. The encapsulation of various antibiotics was carried out as well as a thorough study about the DNA condensation by the metallomicelles. To the best of our knowledge, applications of these metallomicelles have not been shown in the literature yet.4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Name: 4,4′-Dimethyl-2,2′-bipyridine) was used in this study.

《Direct Femtosecond Laser Printing of Silk Fibroin Microstructures》 was written by Santos, Moliria V.; Paula, Kelly T.; de Andrade, Marcelo B.; Gomes, Emmanuel M.; Marques, Lippy F.; Ribeiro, Sidney J. L.; Mendonca, Cleber R.. Application In Synthesis of 4,4′-Dimethyl-2,2′-bipyridine And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

Fabrication of functional silk fibroin microstructures has extensive applications in biotechnol. and photonics. Considerable progress has been made based on lithog. methods and self-assembly approaches. However, most methods require chem. modification of silk fibroin, which restricts the functionalities of the designed materials. At the same time, femtosecond laser-induced forward transfer (fs-LIFT) has been explored as a simple and attractive processing tool for microprinting of high-resolution structures. The authors propose the use of LIFT with fs-pulses for creating high-resolution structures of regenerated silk fibroin (SF). Furthermore, upon adding Eu3+/Tb3+ complexes to SF, the authors have been able to demonstrate the printing by LIFT of luminescent SF structures with a resolution ∼2μm and without material degradation This approach provides a facile method for printing well-defined two-dimensional (2D) micropatterns of pure and functionalized SF, which can be used in a wide range of optical and biomedical applications.

《An Insight into the Kinetics and Mechanism of Oxidation of Tris(4,4′-dimethyl-2,2′-bipyridine)iron(II) by Bromate》 was written by Shazia Summer; Shamim, Afshan; Khattak, Rozina; Qamar, Noshab; Naqvi, Iftikhar Imam. Quality Control of 4,4′-Dimethyl-2,2′-bipyridine And the article was included in Russian Journal of Physical Chemistry A in 2020. The article conveys some information:

Kinetic investigation of oxidation of tris(4,4′-dimethyl, 2,2′-bipyridine)iron(II) by bromate has been undertaken. The redox reaction between [Fe(dmbpy)3]2+ and bromate ion (BrO-3) was monitored spectrophotometrically under the pseudo-first order condition i.e.[BrO-3] ≫ [Fe(dmbpy)3]2+. Kinetic data revealed that the pseudo first order rate constant (kobs) is independent of the concentration of [Fe(dmbpy)3]2+. Though, when concentration of bromate ion is increased in reaction mixture at fixed pH, the rate also increases up to the saturation point at higher concentrations, indicating a precursor complex formation and an outer-sphere mechanism. The influence of accelerating [H+] and ionic strength on reaction rate were also investigated. The increasing values of the rate constant at low pH mention the involvement of protonated bromate species (HBrO3 and H2BrO+3) in the rate-determining step. However, a rise in the value of the rate constant with increasing ionic strength implies the diprotonated species, H2BrO+3, as the reactive species. On the basis of these conclusions, we were able to postulate the appropriate mechanism and the rate law of this redox reaction. The experimental part of the paper was very detailed, including the reaction process of 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Quality Control of 4,4′-Dimethyl-2,2′-bipyridine)

《The laser-induced potential jump: A method for rapid electron injection into oxidoreductase enzymes》 was written by Sanchez, Monica L. K.; Konecny, Sara E.; Narehood, Sarah M.; Reijerse, Edward J.; Lubitz, Wolfgang; Birrell, James A.; Dyer, R. Brian. Application of 1134-35-6 And the article was included in Journal of Physical Chemistry B in 2020. The article conveys some information:

Oxidoreductase enzymes often perform technol. useful chem. transformations using abundant metal cofactors with high efficiency under ambient conditions. The understanding of the catalytic mechanism of these enzymes is, however, highly dependent on the availability of well-characterized and optimized time-resolved anal. techniques. We have developed an approach for rapidly injecting electrons into a catalytic system using a photoactivated nanomaterial in combination with a range of redox mediators to produce a potential jump in solution, which then initiates turnover via electron transfer (ET) to the catalyst. The ET events at the nanomaterial-mediator-catalyst interfaces are, however, highly sensitive to the exptl. conditions such as photon flux, relative concentrations of system components, and pH. Here, we present a systematic optimization of these exptl. parameters for a specific catalytic system, namely, [FeFe] hydrogenase from Chlamydomonas reinhardtii (CrHydA1). The developed strategies can, however, be applied in the study of a wide variety of oxidoreductase enzymes. Our potential jump system consists of CdSe/CdS core-shell nanorods as a photosensitizer and a series of substituted bipyridinium salts as mediators with redox potentials in the range from -550 to -670 mV (vs. SHE). With these components, we screened the effect of pH, mediator concentration, protein concentration, photosensitizer concentration, and photon flux on steady-state photoreduction and hydrogen production as well as ET and potential jump efficiency. By manipulating these exptl. conditions, we show the potential of simple modifications to improve the tunability of the potential jump for application to study oxidoreductases.

Bodedla, Govardhana Babu; Tritton, Daniel Nnaemaka; Chen, Xi; Zhao, Jianzhang; Guo, Zeling; Leung, Ken Cham-Fai; Wong, Wai-Yeung; Zhu, Xunjin published an article in 2021. The article was titled 《Cocatalyst-free Photocatalytic Hydrogen Evolution with Simple Heteroleptic Iridium(III) Complexes》, and you may find the article in ACS Applied Energy Materials.Computed Properties of C12H12N2 The information in the text is summarized as follows:

A simple heteroleptic iridium(III) photosensitizer, Ir-1, containing two ligands 5-(trifluoromethyl)-2-phenylpyridine (ĈN-CF3) and bipyridine (N̂N) has for the first time been studied for cocatalyst-free photocatalytic hydrogen evolution (PHE). The complex Ir-1 produces a hydrogen production rate (ηH2) of 3.2 mmol g-1 h-1, which is over 3.6-fold higher than that of the control complex Ir-2 (0.9 mmol g-1 h-1) containing bipyridine and 2-phenylpyridine ligands without CF3 groups. The higher ηH2 of Ir-1 could be ascribed to the high light-harvesting property, longer triplet electron lifetime, and more appropriate driving force for accepting electrons from the sacrificial donor, which enable efficient charge separation and transfer of electrons for hydrogen evolution. Addnl., the photostability issues of Ir-1 and Ir-2 are addressed by the selection of suitable organic solvent/water photocatalytic systems. In the experiment, the researchers used 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Computed Properties of C12H12N2)
