Han, Ming; Liu, Yuwei; Qian, Dong-Jin; Lee, Yong-Ill; Liu, Hong-Guo published an article in 2021. The article was titled 《Large-Area Assembly of Metal-Organic Layered Ultrathin Films at the Liquid/Liquid Interface》, and you may find the article in Langmuir.Electric Literature of C12H12N2 The information in the text is summarized as follows:

Two-dimensional functional metal-organic frameworks and coordination polymers have attracted much attention and have been successfully prepared in solutions and at interfaces through the coordination of ligands to metal ions. However, the preparation of large-area ultrathin ordered films is still a challenge. Here, a modified liquid/liquid interfacial epitaxial growth method has been developed. A planar liquid/liquid interface between a chloroform solution of bipyridine derivatives and pure water was constructed first, and then an aqueous solution of Eu3+ or Cu2+ ions was added dropwise into the water phase. A layered ultrathin film with the size of several hundreds of square micrometers appeared at the liquid/liquid interface after a certain time. The monitoring results showed that the formation of ultrathin films was a result of continuous epitaxial growth of the adsorbed species due to the synergistic effects of hydrophobic effects of the alkyl chains, coordination bonds between the ligands and metal ions, π-π interactions between the ligands, and the restriction of the interface on the vertical growth. This offers a way to fabricate more large-area thin films of amphiphilic mols. 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: 1134-35-6Electric Literature of C12H12N2) was used in this study.

Synthetic Route of C12H12N2In 2019 ,《Structure-property relationships: “”Double-tail versus double-flap”” ruthenium complex structures for high efficiency dye-sensitized solar cells》 was published in Solar Energy. The article was written by Su, Rui; Ashraf, Saba; El-Shafei, Ahmed. The article contains the following contents:

Six novel heteroleptic amphiphilic polypyridyl Ruthenium (II) complexes, coded FS01-FS06, with hetero-aromatic electron-donor ancillary ligands containing julolidine-derived moieties were synthesized to investigate the relationship between structure modulations of electron donors of Ru(II) dyes and their photophys., electrochem. and photovoltaic properties for dye-sensitized solar cells (DSSCs). These modulations include: Ru(II) complexes with double “”tails”” (i.e. tetra-Me groups attached to the end of julolidine-based antennas, FS04) compared to the ones without double “”tails”” (FS01); complexes with double small “”flaps”” (i.e. small acyclic electron donor auxochromes ortho to the CH = CH bridge of stilbazole, FS02, FS05) compared to the ones with double large “”flaps”” (FS03, FS06). Their low energy metal-to-ligand charge transfers (MLCT) band and molar absorptivities were all better than those of the benchmark, N719. It was also shown that the incorporation of double “”flaps”” into the ancillary ligands caused a slight red shift of light absorption. The photovoltaic properties were evaluated under 1.5 AM standard illumination condition and compared to N719. The highest photocurrent d. (JSC) was observed for the complex with double “”tails”” and double small “”flaps”” (FS05). The overall conversion efficiency for devices employing julolidine-derived Ru (II) complexes was in the following order FS05 > FS02 > FS04 > FS01 > FS06 > FS03. FS05 (8.16%) outperformed the benchmark N719 (7.75%) in the photovoltaic performance, which is due to its best light-harvesting ability, highest molar extinction coefficient and smallest energy band gap among all the six dyes. To probe the interrelationship among julolidine-based electron donors of ancillary ligands, photocurrent and photovoltage of these dyes, the equilibrium mol. geometries of the ancillary ligands were calculated using DFT. The equilibrium mol. geometries of these dyes the photocurrent and photovoltage are dependent on the donating effect of alkyloxy auxochromes, the steric effect generated from the auxochromes and julolidine moieties, and the orientation of longer alkyloxy group. The introduction of double “”tails”” resulted in less dye aggregation and higher charge recombination resistance, leading to higher photocurrents and photovoltages in the solar cell performances. Despite of the donating effect of alkyloxy groups, the bulky double “”flaps”” mainly jammed the hole transportation between the redox couple of the electrolyte and the HOMO of thiocyanate groups (-NCS), translating into the decrease of photocurrent.

The article was titled 《Complexes of lanthanides(III) with mixed 2,2′-bipyridyl and 5,7-dibromo-8-quinolinoline chelating ligands as a new class of promising anti-cancer agents》. The information in the text is summarized as follows:

Five novel lanthanides(III) complexes, [Lu(Me)(MBrQ)2NO3] (MeMBrQ-Lu), [Ho(MeO)(MBrQ)2NO3] (MeOMBrQ-Ho), [Ho(Me)(MBrQ)2NO3] (MeMBrQ-Ho), [La(Me)2(BrQ)2NO3] (MeBrQ-La) and [Sm(Me)(BrQ)2(CH3OH)NO3] (MeBrQ-Sm) were synthesized in which 2,2′-bipyridyl (4,4′-dimethyl-2,2′-bipyridyl (Me) and 4,4′-dimethoxy-2,2′-bipyridine (MeO)) and 5,7-dibromo-8-quinolinoline derivatives (5,7-dibromo-2-methyl-8-quinolinol (MBrQ-H) and 5,7-dibromo-8-quinolinol (BrQ-H)) act as chelating ligands. The in vitro cytotoxic activities of five Ln(III) complexes have been studied with SK-OV-3/DDP, NCI-H460 and HeLa cancer cells. MeMBrQ-Lu, MeOMBrQ-Ho, MeMBrQ-Ho, MeBrQ-La and MeBrQ-Sm show higher cytotoxicity against the HeLa cells than cisplatin (13.11 ± 0.53 μM). In particular, the MeOMBrQ-Ho and MeMBrQ-Ho complexes exhibit superior cytotoxic activity, with IC50 values at 1.00 ± 0.34 nM and 125.00 ± 1.08 nM. We further demonstrate that MeOMBrQ-Ho and MeMBrQ-Ho inhibit the proliferation of HeLa cells by inhibiting telomerase and targeting mitochondria to induce DNA damage-mediated apoptosis. In addition, MeOMBrQ-Ho significantly inhibits tumor growth with a tumor growth inhibition rate (IR) of 50.8% in a HeLa mouse xenograft model. Taken together, MeOMBrQ-Ho is a novel lanthanide(III) complex with promising antitumor activity.

Electric Literature of C12H12N2In 2022 ,《A self-oscillating gel system with complex dynamic behavior based on a time delay between the oscillations》 was published in Soft Matter. The article was written by Li, Xiuchen; Li, Jie; Zheng, Zhaohui; Deng, Jinni; Pan, Yi; Ding, Xiaobin. The article contains the following contents:

The time delay existing between the chem. oscillation and mech. oscillation (C-M delay) in a self-oscillating gel (SOG) system is observable in previous exptl. studies. However, how the C-M delay affects the dynamic behavior of a large anisotropic SOG has not been quantified or reported systematically. In this study, we observed that the oscillation period increases with a decrease in the crosslinking d. of the anisotropic SOG, and this determined whether regular mech. oscillation occurs. Unlike before, the disrupted mech. oscillations interestingly tend to be regular and periodic under visible light, which is an inhibitor for the B-Z reaction incorporating the Ru complex as a catalyst (Ru-BZ reaction). Moreover, the study of the C-M delay at different scales has far-reaching implications for intelligent soft actuators.

The title of the article was 《Solution-Processed Yellow Organic Light-Emitting Diodes Based on Two New Ionic Ir (III) Complexes》.Name: 4,4′-Dimethyl-2,2′-bipyridine The author mentioned the following in the article:

Two new and efficient cationic yellow-emissive Ir (III) complexes (Ir1 and Ir2) are rationally designed by using 2-(4-chloro-3-(trifluoromethyl)phenyl)-4-methylquinoline as the main ligand, and, resp., 4,4′-dimethyl-2,2′-bipyridyl and 4,4′-dimethoxy-2,2′-bipyridyl as the ancillary ligands. Both complexes show enhanced phosphorescence 546 nm with 572 nm as shoulder and high phosphorescent quantum efficiency in solution, which is in favor of efficient solution-processed phosphorescent organic light-emitting diodes. Compared with Ir2, the Ir1-based device displays excellent device performance, with maximum external quantum efficiency, current efficiency, and power efficiency of up to 7.92%, 26.32 cd/A and 15.31 lm/W, resp., thus proving that the two new ionic Ir (III) complexes exhibit great potential for future solution-processed electroluminescence.

The article was written by Pakhira, Mahuya; Chatterjee, Dhruba P.; Mallick, Dibyendu; Ghosh, Radhakanta; Nandi, Arun K.. The article contains the following contents:

A poly(vinylidine fluoride) graft random copolymer of t-Bu aminoethyl methacrylate (tBAEMA) and oligo(ethylene glycol) Me ether methacrylate (OEGMA, Mn = 300) [PVDF-g-P(tBAEMA-ran-OEGMA), PVBO] is synthesized by atom transfer radical polymerization (ATRP), and PVBO is fractionated to get a highly water-soluble fraction (PVBO-1) showing a reversible on/off fluorescence behavior with gradual increase and decrease in pH, resp., achieving a maximum quantum yield of 0.18 at pH = 12. PVBO-1 dissolved in water shows large multimicellar aggregates (MMcA), but at pH 12, crumbling of larger aggregates to much smaller micelles occurs, forming nonconjugated polymer dots (NCPDs), as supported by transmission electron microscopy and dynamic light scattering study. The reversible fluorescence on/off behavior also occurs with the decrease and increase of temperature Theor. study indicates that, at high pH, most of the amino groups become neutral and exhibit a strong tendency to form aggregates from crowding of a large number of carbonyl and amine groups, minimizing the HOMO-LUMO gap, showing an absorption peak at the visible region, and generating aggregation-induced emission.4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Recommanded Product: 4,4′-Dimethyl-2,2′-bipyridine) was used in this study.

The article was titled 《Microwave-assisted synthesis of ruthenium(II) complexes containing levofloxacin-induced G2/M phase arrest by triggering DNA damage》, and you may find the article in RSC Advances.Safety of 4,4′-Dimethyl-2,2′-bipyridine The information in the text is summarized as follows:

Ru(II) complexes have attracted increasing attention as promising antitumor agents for their relatively low toxicity, high affinity to DNA mols., and correlation with multiple targets. Meanwhile, quinolones are synthetic antibacterial agents widely used in the clin. practice. In this paper, two novel Ru(II) complexes coordinated by levofloxacin (LOFLX), [Ru(bpy)2(LOFLX)]·2ClO4 (1), and [Ru(dmbpy)2(LOFLX)]·2ClO4 (2) (bpy = 2,2′-bipyridine, dmbpy = 4,4′-dimethyl-2,2′-bipyridine) were synthesized with high efficiency under microwave irradiation and characterized by ESI-MS, 1H NMR, and 13C NMR. The binding behavior of these complexes with double-strand calf thymus DNA(CT-DNA) was investigated using spectroscopy, mol. docking, and d. functional theory calculations Results showed that 2 exhibited higher binding affinity than 1 and LOFLX. Further studies showed that 2 could induce the G2/M phase arrest of A549 cells via DNA damage. In summary, these results indicated that 2 could be developed as a potential anticancer agent in treatment of lung cancer through the induction of cell cycle arrest at G2/M phase by triggering DNA damage.

HPLC of Formula: 1134-35-6In 2020 ,《Effect of fluoro-substituted acceptor-based ancillary ligands on the photocurrent and photovoltage in dye-sensitized solar cells》 was published in Solar Energy. The article was written by Ashraf, Saba; Su, Rui; Akhtar, Javeed; Siddiqi, Humaira M.; Shuja, Ahmed; El-Shafei, Ahmed. The article contains the following contents:

Herein, we report four novel heteroleptic ruthenium (II) complexes, namely SD-7 to SD-10, containing fluoro- and trifluoro- Me antennas as substituents on the ancillary ligands for dye-sensitized solar cells, and were compared to the benchmark dye N719. Photosensitizers (dyes) SD-7 to SD-10 were synthesized according to a typical one-pot three-step procedure with the corresponding ancillary ligands (LS-7 to LS-10). All the dyes were characterized by ATR-FTIR, 1H NMR and mass spectrometry. Furthermore, the photophys., electrochem. and photovoltaic performances were compared with N719. The band gaps, ground and excited state oxidation potentials were measured. The photovoltaic performance of the dyes showed that SD-7 with five fluorine atoms and SD-8 with -CF3 at the -ortho position of the Ph moiety outperformed the benchmark dye N719 with the efficiencies of 8.03% and 8.17%, resp., with c.d. of 19.57 and 19.46 mA•cm-2, resp., and open-circuit voltages of 0.65 V and 0.69 V, resp., under optimized conditions. The fabricated solar devices at lab-scale showed a systematic trend of decreasing JSC when the fluoro-substituted dyes were sensitized on TiO2: SD-7 (with five -F) > SD-8 (with one -CF3 at ortho position) > SD-9 (with one -CF3 at para position) > SD-10 (with two -CF3, one at ortho and one at para position). This can be attributed to the greater number of fluorine atoms directly attached to sp2 hybridized carbon atoms, which greatly enhanced the dipole moment and intimate electronic coupling of SD-7 with TiO2 nanoparticles leading to better photocurrent d.

To contribute a solution for the global warming problem, the selective electrochem. reduction of CO2 to CO was studied in the gas phase using a [CO2(g), Co-N-C cathode | Nafion-H | Pt/C anode, H2/water] system without using carbonate solutions The Co-N-C electrocatalysts were synthesized by partial pyrolysis of precursors in inert gas, which were prepared from various N-bidentate ligands, Co(NO3)2, and Ketjenblack (KB). The most active electrocatalyst was Co-(4,4′-dimethyl-2,2′-bipyridine)/KB pyrolyzed at 673 K, denoted Co-4,4′-dmbpy/KB(673K). A high performance of CO formation (331 μmol h-1 cm-2, 217 TOF h-1) at 0.020 A cm-2 with 78% current efficiency was obtained at -0.75 V (SHE) and 273 K under strong acidic conditions of Nafion-H. Characterization studies using extended X-ray absorption fine structure (EXAFS), XPS, transmission electron microscopy-energy-dispersive X-ray (TEM-EDX), X-ray diffraction (XRD), and temperature-programmed desorption with mass spectrometry (TPD-MS) indicated the active site as Co coordinated with four N atoms bonding the surface of KB, abbreviated Co-N4-Cx structure.

To improve current multiphase white light emitting diodes (WLEDs), a novel series of five complexes consisting of one binary and four ternary complexes that emitted cool white light was successfully synthesized using a chelating tetradentate ligand and auxiliary ligands, i.e. 5,6-dimethyl-1,10-phenanthroline, 1,10-phenanthroline, 4,4′-dimethyl-2,2′-bipyridyl, and 2,2′-bipyridyl. The series was examined structurally using elemental anal., Fourier transform IR spectroscopy, energy dispersive X-ray anal., UV-visible spectroscopy, and proton NMR spectroscopy. These complexes had the appropriate thermal stability required for the generation of white organic LEDs (WOLEDs). Dysprosium (III) (Dy3+) ion complexes demonstrated the characteristic emission peaks of blue color at 482 nm and yellow color at 572 nm, resp., when excited using near UV light. Band gap, refractive index, and decay lifetime of the optimized samples were recorded as 2.68 eV, 2.12, and 1.601 ms, resp. Correlated color temperature value (7875 K), Commission International de l′Eclairage coordinates (0.300, 0.294), and color purity (21.04 x 10-2) of the optimized complex were near to those of white illuminants as defined by the National Television System Committee. These complexes had promise as com. LEDs for the advanced optoelectronics devices, especially as WOLEDs for illumination applications.
