The structure of this type of complex is unique in that the solvent ethanol mol. participates in the coordination. Complexes 1-2 are stitched together via π-π stacking interactions and hydrogen bonding interactions to form the 1D, 2D supramol. structures. The thermal decomposition mechanisms of two complexes were obtained by TG-DSC/FTIR techniques. The molar heat capacities of the complexes 1 and 2 are measured by a DSC instrument over the temperature range from 255.15 to 323.15 K and thermodn. functions were calculated by fitted polynomial and thermodn. equations. The luminescence studies demonstrate that complex 2 exhibits the characteristic emission of Tb3+ ion (5D4 → 7F6-3).

In present study, new three-arm initiator containing coumarin group and new 4-(3-(4-methoxyphenyl)acryloyl) Ph acrylate (MPAC) was synthesized. Three-armed star-shaped polymer was obtained by polymerization using ATRP method from the chlorine ends of the initiator. The structure characterization was performed by FT-IR, 1H-NMR, 13C-NMR spectroscopy techniques. Thermal analyzes were performed by using thermogravimetry (TGA) and differential scanning calorimetry anal. (DSC) techniques in a nitrogen atm. Thermal decomposition activation energy (Ea) of star polymer was determined by the Flynn-Wall-Ozawa and Kissinger methods. The average activation energy in the range of 0.02-0.3 conversion range was determined as 115.28 kJ/mol and 152.72 kJ/mol, resp. Polymer composites were prepared by adding graphene particles in different ratios (0.5%, 1.0%, 2.0%, and 4.0% by weight) to the polymer matrix. The dielec. properties of star polymer and graphene composites were investigated in a range of 100 Hz-20 kHz frequency. Besides, the dielec. properties of the pure polymer were examined as a function of frequency at different temperatures (25°C, 40°C, 55°C, 70°C,).

A compound: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, Journal of Materials Chemistry C: Materials for Optical and Electronic Devices called Molecular engineering towards tunable morphology of metal-organic complex microcrystals for efficient and multicolor electrochemiluminescence, Author is Ding, Chun-Yun; Shao, Jiang-Yang; Gong, Zhong-Liang; Zhong, Yu-Wu; Yao, Jiannian, the main research direction is mol engineering towards tunable morphol metal organic complex microcrystals; multicolor electrochemiluminescence.Computed Properties of C12H12N2.

Electrochemiluminescence (ECL) of crystalline materials has recently attracted increasing attention due to their unique characteristics and applications, such as crystallization-induced emission, active waveguiding, and biosensing. Tris(2,2′-bipyridine)ruthenium(II), [Ru(bpy)3]2+, a classical metal-organic complex for ECL studies, has been fully investigated in solution as well as its derivatives However, the dependence of ECL properties on the mol. structure and crystal morphol. of these complexes has not been illustrated, partially due to the difficulty in the controlled crystal growth. Here, we adopt a facile mol. engineering strategy to obtain microcrystals of [Ru(bpy)3]2+ derivatives with well-defined morphol. (rods, wires, or polyhedrons) and varied phosphorescence emission colors (yellow, orange, and red) by simply changing the position and number of Me substituents on the bipyridine ligands. The packing modes of mols. influenced by Me groups play a vital role in crystal growth based on attachment energy anal. The obtained microcrystals could act as ECL luminophores when modified on glassy carbon electrode surfaces. Those with one-dimensional (1D) morphol. generally show superior ECL efficiency and stability to three-dimensional (3D) shaped microcrystals. ECL biosensors made of stable 1D microcrystals show reliable and sensitive responses to hydroxyproline, demonstrating their capacity in recyclable detections. This work demonstrates the great potential of mol. engineering in controlling the morphol., emission colors, and ECL properties of mol. crystals, paving the way for the development of high-performance ECL biosensing and optoelectronic devices.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Ru(II)/N-N/PPh3 complexes as potential anticancer agents against MDA-MB-231 cancer cells (N-N = diimine or diamine), the main research direction is ruthenium dipyridylamine diimine complex preparation crystal structure; electrochem antitumor activity lipophilicity ruthenium dipyridylamine diimine complex; DNA HSA binding ruthenium dipyridylamine diimine complex.Quality Control of 5,5′-Dimethyl-2,2′-bipyridine.

The rational design of anticancer agents that acts in specific biol. targets is one of the most effective strategies for developing chemotherapeutic agents. Aiming at obtaining new ruthenium(II) compounds with good cytotoxicity against tumor cells, a series of new complexes of general formula [RuCl(PPh3)(Hdpa)(N-N)]Cl [PPh3 = triphenylphosphine, N-N = 2,2′-dipyridylamine (Hdpa) (1), 1,2-diaminoethane (en) (2), 2,2′-bipyridine (bipy) (3), 5,5′-dimethyl-2,2′-bipyridine (dmbipy) (4), 1,10-phenanthroline (phen) (5) and 4,7-diphenyl-1,10-phenanthroline (dphphen) (6)] were synthesized. The complexes were characterized by elemental anal. and spectroscopic techniques (IR, UV/Visible, and 1D and 2D NMR) and three of their x-ray structures were determined: [RuCl(PPh3)(Hdpa)2]Cl, [RuCl(PPh3)(Hdpa)(en)]Cl and [RuCl(PPh3)(Hdpa)(dmbipy)]Cl. All the complexes are more cytotoxic against the cancer cell line than against the non-tumor cell line, highlighting complexes 1 and 5, which have an index selectivity of 18 and 15, resp. The binding constants of compounds 1-6 with human serum albumin (HSA) were determined by tryptophan fluorescence quenching, indicating moderate to strong interactions. The binding mode of the complexes to calf thymus (CT) DNA was explored by several techniques, which reveal that only the dphphen compound 6 causes distortions in the secondary and tertiary structures of DNA. The nature of the N-N co-ligand and the presence of the PPh3 and Hdpa ligands are features that can influence the binding affinity of the complexes by the biomols. and in the cytotoxic activity of the complexes. Overall, the complexes with diimine co-ligand are much more cytotoxic than compound 2 with the aliphatic diamine.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Group 6 Metal Complexes as Electrocatalysts of CO2 Reduction: Strong Substituent Control of the Reduction Path of [Mo(η3-allyl)(CO)2(x,x’-dimethyl-2,2′-bipyridine)(NCS)] (x = 4-6), the main research direction is methylbipyridine allyl molybdenum carbonyl complex preparation redox potential DFT; crystal structure methylbipyridine allyl molybdenum carbonyl complex; mol structure methylbipyridine allyl molybdenum carbonyl complex; optimized geometry bipyridine allylmolybdenum complex anion radical complex DFT.Related Products of 1762-34-1.

[Mo(η3-allyl)(CO)2(x,x’-dmbipy)(NCS)] (dmbipy = dimethyl-2,2′-bipyridine; x = 4-6) were synthesized and their electrochem. reduction studied using combined cyclic voltammetry (CV) and variable-temperature spectroelectrochem. (IR/UV-visible SEC) in THF and butyronitrile (PrCN), at Au and Pt electrodes. The exptl. results, strongly supported by d. functional theory (DFT) calculations, indicate that the general cathodic path of these Group 6 organometallic complexes is closely related to that of the intensively studied class of Mn tricarbonyl α-diimine complexes, which, themselves, have recently been identified as important smart materials for catalytic CO2 reduction The di-Me substitution on the 2,2′-bipyridine ligand backbone has presented new insights into this emerging class of catalysts. For the 1st time, the 2e- reduced 5-coordinate anions [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- were directly observed with IR spectroelectrochem. (IR SEC). The role of steric and electronic effects in determining the reduction-induced reactivity was also studied. For the 6,6′-dmbipy, the primary 1e- reduced radical anions exert unusual stability, radically changing the follow-up cathodic path. The 5-coordinate anion [Mo(η3-allyl)(CO)2(6,6′-dmbipy)]- remains stable at low temperature in strongly coordinating butyronitrile and does not undergo dimerization at elevated temperature, in sharp contrast to reactive [Mo(η3-allyl)(CO)2(4,4′-dmbipy)]- that tends to dimerize in a reaction with the parent complex. The complex with the 5,5′-dmbipy ligand combines both types of reactivity. Under aprotic conditions, the different properties of [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- are also reflected in their reactivity toward CO2. Preliminary CV and IR SEC results reveal differences in the strength of CO2 coordination at the free axial position. Catalytic waves attributed to the generation of the 5-coordinate anions were observed using CV, but only a modest catalytic performance toward the production of formate was demonstrated by IR SEC. For 6,6′-dmbipy, a stronger catalytic effect was observed for the Au cathode, compared to Pt.

Two novel Sm(III) complexes, [Sm(3,4-DMBA)3(3,4-DMHBA)(5,5′-DM-2,2′-bipy)]2 (1), [Sm(3-MOBA)3(5,5′-DM-2,2′-bipy)]2 (2) (3,4-dimethylbenzoic acid = 3,4-DMHBA, 3-methoxybenzoic acid = 3-MOHBA and 5,5′-dimethyl-2,2′-bipyridine = 5,5′-DM-2,2′-bipy), were successfully synthesized and assembled. The crystal structures were determined by single crystal x-ray diffraction. Two complexes were characterized by the elemental anal., IR, powder x-ray diffraction, thermal gravimetric technol. Because of the different ligands, the structures of the two complexes are very different, especially the structure of the complex 1. Each central Sm(III) ion of complex 1 was coordinated by three deprotonated 3,4-DMBA-,one unprotonated 3,4-DMHBA and one 5,5′-DM-2,2′-bipy, which has rarely been reported before. However each central Sm(III) ion of complex 2 was only coordinated via three deprotonated 3-MOBA- and one 5,5′-DM-2,2′-bipy. In addition, the thermal decomposition mechanism and the three-dimensional IR accumulation spectra of the evolved gas during the thermal decomposition for two complexes were studied by the simultaneous TG/DSC-FTIR technol. What’s more, the luminescence properties of two complexes are also discussed. Finally, the bacteriostatic activities of two complexes were evaluated against Staphlococcus aureus, Escherichia coli and Candida albicans.
