The article was titled 《A higher voltage Fe(II) bipyridine complex for non-aqueous redox flow batteries》, and you may find the article in Dalton Transactions.Related Products of 1134-35-6 The information in the text is summarized as follows:

Non-aqueous redox flow batteries (RFBs) offer the possibility of higher voltage and a wider working temperature range than their aqueous counterpart. Here, we optimize the established 2.26 V Fe(bpy)3(BF4)2/Ni(bpy)3(BF4)2 asym. RFB to lessen capacity fade and improve energy efficiency over 20 cycles. We also prepared a family of substituted Fe(bpyR)3(BF4)2 complexes (R = -CF3, -CO2Me, -Br, -H, -tBu, -Me, -OMe, -NH2) to potentially achieve a higher voltage RFB by systematically tuning the redox potential of Fe(bpyR)3(BF4)2, from 0.94 V vs. Ag/AgCl for R = OMe to 1.65 V vs. Ag/AgCl for R = CF3 (ΔV = 0.7 V). A series of electronically diverse sym. and asym. RFBs were compared and contrasted to study electroactive species stability and efficiency, in which the unsubstituted Fe(bpy)3(BF4)2 exhibited the highest stability as a catholyte in both sym. and asym. cells with voltage and coulombic efficiencies of 94.0% and 96.5%, and 90.7% and 80.7%, resp.

Salomon, Fernando F.; Vega, Nadia C.; Jurado, Jose Piers; Moran Vieyra, Faustino E.; Tirado, Monica; Comedi, David; Campoy-Quiles, Mariano; Cattaneo, Mauricio; Katz, Nestor E. published an article in 2021. The article was titled 《Heteroleptic Ruthenium(II) Complexes with 2,2′-Bipyridines Having Carbonitriles as Anchoring Groups for ZnO Surfaces: Syntheses, Physicochemical Properties, and Applications in Organic Solar Cells》, and you may find the article in Inorganic Chemistry.Related Products of 1134-35-6 The information in the text is summarized as follows:

Heteroleptic ruthenium (II) complexes were used for sensitizing ZnO surfaces in organic solar cells (OSCs) as mediators with photoactive layers. The complexes [Ru(4,4′-X2-bpy)(Mebpy-CN)2]2+ (with X = -CH3, -OCH3 and -N(CH3)2; bpy = 2,2′-bipyridine; Mebpy-CN = 4-methyl-2,2′-bipyridine-4′-carbonitrile) were synthesized and studied by anal. and spectroscopical techniques. Spectroscopic, photophys., and electrochem. properties were tuned by changing the electron-donating ability of the -X substituents at the 4,4′-positions of the bpy ring and rationalized by quantum mech. calculations These complexes were attached through nitrile groups to ZnO as interfacial layer in an OSC device with a PBDB-T:ITIC photoactive layer. This modified inorganic electron transport layer generates enhancement in photoconversion of the solar cells, reaching up to a 23% increase with respect to the unsensitized OSCs. The introduction of these dyes suppresses some degradative reactions of the nonfullerene acceptor due to the photocatalytic activity of zinc oxide, which was maintained stable for about 11 mo. Improving OSC efficiencies and stabilities can thus be achieved by a judicious combination of new inorganic and organic materials.

Mixed-ligand copper(II) complexes based on 1,10-phenanthroline and related compounds are of interest to scientists due to their promising anticancer properties. In this study, four new water-soluble copper(II) complexes [Cu(dmbipy)L2], [Cu(phen)(H2O)L2], [Cu(dmphen)L2] and [Cu2(bipy)2L4], where HL – 4,5-dichloro-isothiazole-3-carboxylic acid, bipy = 2,2′-bipyridine, dmbipy = 2,2′-bi-4-picoline, phen = 1,10-phenanthroline, dmphen = 4,7-dimethyl-1,10-phenanthroline are reported. All complexes have been characterized by elemental and powder x-ray diffraction anal., EPR and IR-spectroscopy. Mol. structures of the reported complexes have been determined by single crystal x-ray diffraction. Copper(II) ion, HL and heterocyclic N-donor ligands have been found to form 1:2:1 complexes that possess square bipyramid or square pyramidal geometry. The UV-vis spectroscopy and mass spectrometry have been applied to show the behavior of the compounds in solution All complexes have been screened in vitro for their cytotoxic activity against Hep-2 and MCF-7 cell lines. They exhibit significant dose-dependent cytotoxic effect and [Cu(dmphen)L2] is the most cytotoxic (IC50 = 0.97 ± 0.03μM when compared to IC50 = 9.2 ± 0.5μM for control, cisplatin – Hep-2 cell line). The investigation of DNA binding ability by UV-vis titration technique indicates that complexes obtained exhibit moderate binding affinity toward calf thymus DNA. Effect of [Cu(dmbipy)L2] and [Cu(dmphen)L2] on activity of drug-metabolizing enzymes cytochromes P 450 has also been investigated. The addition of complexes to the hepatic microsomes of 3-MC or PB-treated rat, lead to a dose-dependent decrease of CYP’s activities. The data obtained indicate that [Cu(dmphen)L2] and [Cu(phen)(H2O)L2] can be potential anticancer agents.

The article was titled 《Organic moiety-regulated Photocatalytic Performance of Phosphomolybdate hybrids for hexavalent chromium reduction》, and you may find the article in Chemistry – An Asian Journal.Formula: C12H12N2 The information in the text is summarized as follows:

Visible-light-driven photocatalytic Cr(VI) reduction is a promising pathway to moderate environmental pollution, in which the development of photocatalysts is pivotal. Herein, three hourglass-type phosphomolybdate-based hybrids with the formula of: (H2bpe)3[Zn(H2PO4)][Zn(bpe)(H2O)2]H{Zn[P4Mo6O31H6]2}·6H2O (1) Na6[H2bz]2[ZnNa4(H2O)5]{Zn [P4Mo6O31H3]2}·2H2O (2) and (H2mbpy) {[Zn(mbpy)(H2O)]2[Zn(H2O)]2}{Zn[P4Mo6O31H6]2}·10H2O (3) (bpe = trans-1,2-bi(4-pyridyl)-ethylene; bz = 4,4′-diaminobiphenyl; mbpy = 4,4′-dimethyl-2,2′bipyridine) were synthesized under the guidance of the functional organic moiety modification strategy. Structural anal. showed that hybrids 1-3 have similar 2D layer-like spatial arrangements constructed by {Zn[P4Mo6]2} clusters and organic components with different conjugated degree. With excellent redox properties and wide visible-light absorption capacities, hybrids 1-3 display favorable photocatalytic activity for Cr(VI) reduction with 79%, 70% and 64% reduction rates, which are superior to that of only inorganic {Zn[P4Mo6]2} itself (21%). The investigation of organic components on photocatalytic performance of hybrids 1-3 suggested that the organic counter cations (bpe, bz and mbpy) can effectively affect the visible-light absorption, as well as the recombination of photogenerated carriers stemmed from {Zn[P4Mo6]2} clusters, further promoting their photocatalytic performances towards Cr(VI) reduction This work provides an exptl. basis for the design of functionalized photocatalysts via the modification of organic species.

Category: pyridine-derivativesIn 2019 ,《Electrochemical and electronic properties of a series of substituted polypyridine ligands and their Co(II) complexes》 appeared in Inorganica Chimica Acta. The author of the article were Ferreira, Hendrik; Conradie, Marrigje M.; Conradie, Jeanet. The article conveys some information:

DFT calculations show that, due to Jahn-Teller distortion, the d7 [Co(N,N)3]2+ complexes, with S = 1/2 (N,N = bipyridine or substituted bipyridine ligand) have two longer axial and four shorter equatorial Co-N bonds (elongation Jahn-Teller), while [Co(terpyridine)2]2+ with S = 1/2, instead has two shorter central (axial) Co-N bonds and four longer distal Co-N bonds (compression Jahn-Teller), since in the latter, the distal Co-N bonds are more flexible than the Co-N axial bonds in the rigid structure of the tridentate terpyridine ligand. The same trend is observed for the related high spin S = 3/2 Co(II) complexes, though less pronounced. The cyclic voltammograms of [Co(terpyridine)2]2+ and a series of the [Co(N,N)3]2+ complexes show at least three chem. as well as electrochem. reversible redox couples, namely CoIII/II, CoII/I and a ligand based reduction of the polypyridine-Co(I) complex. The reduction of the uncoordinated free polypyridine ligand is more than 0.5 V more neg. than the reduction of the coordinated ligand in the polypyridine-Co(I) complex.

Safety of 4,4′-Dimethyl-2,2′-bipyridineIn 2021 ,《Supramolecular photocatalysts fixed on the inside of the polypyrrole layer in dye sensitized molecular photocathodes: application to photocatalytic CO2 reduction coupled with water oxidation》 appeared in Chemical Science. The author of the article were Kuttassery, Fazalurahman; Kumagai, Hiromu; Kamata, Ryutaro; Ebato, Yusuke; Higashi, Masanobu; Suzuki, Hajime; Abe, Ryu; Ishitani, Osamu. The article conveys some information:

The development of systems for photocatalytic CO2 reduction with water as a reductant and solar light as an energy source is one of the most important milestones on the way to artificial photosynthesis. Although such reduction can be performed using dye-sensitized mol. photocathodes comprising metal complexes as redox photosensitizers and catalyst units fixed on a p-type semiconductor electrode, the performance of the corresponding photoelectrochem. cells remains low, e.g., their highest incident photon-to-current conversion efficiency (IPCE) equals 1.2%. Herein, we report a novel dye-sensitized mol. photocathode for photocatalytic CO2 reduction in water featuring a polypyrrole layer, [Ru(diimine)3]2+ as a redox photosensitizer unit, and Ru(diimine)(CO)2Cl2 as the catalyst unit and reveal that the incorporation of the polypyrrole network significantly improves reactivity and durability relative to those of previously reported dye-sensitized mol. photocathodes. The irradiation of the novel photocathode with visible light under low applied bias stably induces the photocatalytic reduction of CO2 to CO and HCOOH with high faradaic efficiency and selectivity (even in aqueous solution), and the highest IPCE is determined as 4.7%. The novel photocathode is coupled with n-type semiconductor photoanodes (CoOx/BiVO4 and RhOx/TaON) to construct full cells that photocatalytically reduce CO2 using water as the reductant upon visible light irradiation as the only energy input at zero bias. The artificial Z-scheme photoelectrochem. cell with the dye-sensitized mol. photocathode achieves the highest energy conversion efficiency of 8.3 × 10-2% under the irradiation of both electrodes with visible light, while a solar to chem. conversion efficiency of 4.2 × 10-2% is achieved for a tandem-type cell using a solar light simulator (AM 1.5, 100 mW cm-2).

Formula: C12H12N2In 2019 ,《Synthesis, structures and spectroscopy of three new lanthanide β-diketonate complexes with 4,4′-dimethyl-2,2′-bipyridine. Near-infrared electroluminescence of ytterbium(III) complex in OLED》 appeared in Inorganica Chimica Acta. The author of the article were Santos, Hudson P.; Gomes, Emmanuel S.; dos Santos, Moliria V.; D’Oliveira, Kaique A.; Cuin, Alexandre; Martins, Jefferson S.; Quirino, Welber G.; Marques, Lippy F.. The article conveys some information:

Three new lanthanide(III) β-diketonate complexes [Ln(btfa)3(4,4′-dmbpy)] (Ln = Yb(III), Gd(III) and Nd(III); btfa = anionic 4,4,4-trifluoro-1-phenyl-1,3-butanedione and 4,4′-dmbpy = 4,4′-dimethyl-2,2′-bipyridine) were synthesized and their characterization, including elemental anal., FTIR spectroscopy and thermal anal. (TG/DTA), is reported. The crystal description based on powder x-ray diffraction reveals that Gd(III) and Yb(III) compounds are isostructural and that lanthanide ion is eight-coordinated by oxygen and nitrogen atoms to give new tris- β-diketonates [Ln(btfa)3(4,4′-dmbpy)]. The cell parameters of Nd(III) complex are close to Gd(III) and Yb(III) ones. Phosphorescence data of Gd(III) complex shows that the triplet states (T1) of the ligands have higher energy than the emitting states of Yb(III) and Nd(III), indicating the possibility of intramol. energy transfer to these metal ions, which exhibit near-IR (NIR) emission. The authors used the Yb(III) complex as an emitting layer (EML) in a near IR organic light emitting diode (NIR-OLED) with the structure: CuPc(15 nm)/XD-03(40 nm)/Yb(60 nm)/BCP(15 nm)/Alq3(10 nm)/Al(120 nm). OLEDs exhibit both visible electroluminescence and a NIR electroluminescence at 980 nm from the 2F5/2 → 2F7/2 transition of the Yb(III).

And the article was published in Inorganica Chimica Acta in 2019. HPLC of Formula: 1134-35-6 The author mentioned the following in the article:

Four novel Ni(II) complexes, [Ni(dppmO,O)2(NCS)2] (1), [Ni(dppmO,O)3][NiCl4] (2), [Ni(dmbpy)(H2O)2Br2] (3) and [Ni(dppmO,O)3][NiCl4]·[Ni(dppm)Cl2] (4) (dppm = bis(diphenylphosphino)methane, dppmO,O = bis(diphenylphosphanoxido)methane, dmbpy = 4,4′-dimethyl-2,2′-bipyridine), were synthesized and structurally and magnetically characterized. 1 And 3 are pseudooctahedral, while 2 and 4 are unique due to the existence of hexa- or tetracoordination in two/three independent Ni(II) atoms. For hexacoordinated systems the magnetic data confirm small magnetic anisotropy expressed through the axial zero-field splitting parameter D/hc = -4.5 to +4.4 cm-1. For [NiCl4]2- tetrahedral units (in complexes 2 and 4) the magnetic anisotropy is substantially larger. Exptl. findings were confirmed by ab initio calculations and forwarded to magnetostructural D-correlations.

And the article was published in Journal of Luminescence in 2019. Application of 1134-35-6 The author mentioned the following in the article:

In this work, we present the synthesis, solid state characterization and complete photoluminescence study of new important homobimetallic lanthanide complexes containing the non-steroidal anti-inflammatory drug (NSAID) naproxen. The anal. and spectroscopic techniques reveals the formation of eight compounds of general formula [Ln2(nap)6(H2O)4] (Eu 1 and Gd 2), [Ln2(nap)6(bpy)2] (Eu 3 and Gd 4), [Ln2(nap)6(4,4′-dmbpy)2] (Eu 5 and Gd 6) and [Ln2(nap)6(phen)2] (Eu 7 and Gd 8), where: nap = naproxen ligand, bpy =2,2′-bipyridine, 4,4′-dmbpy = 4,4′-dimethyl-2,2′-bipyridine and phen = 1,10-phenanthroline. Using the RM1 model, the mol. structures of the EuIII complexes were calculated, with your optimized ground state geometries used to obtain all details involved in the energy transfer process. From the resp. GdIII complexes were obtained the lowest ligand triplet states, proving that the photoluminescence in the EuIII naproxen complexes is proposed to be a ligand sensitized luminescence process. On the other hand, the position of the triplet states also explains the non-effective energy transfer in the TbIII naproxen complexes. The presence of N,N-donors ligands (bpy, 4,4′-dmbpy and phen) results in an 3-4-fold increase in the quantum efficiency when compared with the EuIII complex without nitrogen ligands. The high values of emission quantum efficiency (η ∼ 70 – 98%) show the EuIII complexes can be potential candidates as emitters in biol. assays. After reading the article, we found that the author used 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Application of 1134-35-6)
