SDS of cas: 1762-34-1. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Two nonporous MOFs with uncoordinated carboxylate groups: Fillers for enhancing the proton conductivities of nafion membrane. Author is Li, Rong-Yun; Liu, Hou-Ting; Chu, Zhi-Tong; Zhou, Chuan-Cong; Lu, Jing; Wang, Su-Na.

Two nonporous MOFs [Ni(L)0.5 (Mbpy)(H2O)2]2 (1) and [Cd(H2L)(Mbpy)]n (2) (H4L = 5,5′-(butane-1,4-diylbis (oxy))diisophthalic acid, Mbpy = 5,5′-dimethyl-2,2′-bipyridine) were obtained through hydrothermal reactions under different pH values reaction condition. Structure analyses reveal that there are uncoordinated deprotonated and protonated carboxylate groups in compounds 1 and 2, resp., which are confirmed by IR spectra. The XRD and TG studies indicate that both of compounds exhibit good water and thermal stability. The proton conductivities of the Nafion membrane doped by compounds 1 and 2 were studied. Compound 2 can enhance the proton conductivity of the composite membrane ∼29% higher than that of pure Nafion. The water uptakes of 1/Nafion and 2/Nafion composite membrane are similar and slightly higher than that of pure Nafion membrane. The apparently high proton conductivity of 2/Nafion membrane should be attributed to the high proton d. of 2 framework, which is resulted by the protonated uncoordinated carboxylate acid groups.

A series of five mononuclear β-diketonate-Dy(III) complexes, with formulas Dy(ntfa)3(Br-bpy) (1), Dy(ntfa)3(Br2-bpy) (2), Dy(ntfa)3(5,5-(CH3)2-bpy) (3), Dy(ntfa)3(4,4-((CH3)3)2-bpy) (4) and Dy(ntfa)3(4,4-(CH3)2-bpy) (5) (ntfa = 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione, Br-bpy = 5-bromo-2,2′-bipyridine, Br2-bpy = 4,4′-dibromo-2,2′-bipyridine, 5,5-(CH3)2-bpy = 5,5′-di-methyl-2,2′-bipyridine, 4,4-((CH3)3)2-bpy = 4,4′-di-tert-butyl-2,2′-bipyridine, and 4,4-(CH3)2-bpy = 4,4′-di-methyl-2,2′-bipyridine), have been prepared by altering the capping N-donor coligands. Dy(III) ions in all complexes possess N2O6 octa-coordinated environments, displaying a distorted square antiprismatic D4d symmetry in complexes 1-4, as well as a triangular dodecahedron D2d symmetry in 5. Magnetic investigations evidence the SIM behavior in the five complexes with the energy barriers (Ueff) of 104.19 K (1), 122.93 K (2), 84.20 K (3), 64.16 K (4) and 80.23 K (5) under zero applied dc field. The potential QTM effects in the title complexes are successfully suppressed in the presence of the extra applied fields. The crystal field parameters and orientations of the magnetic easy axes were obtained from the simulation of the magnetic data and the electrostatic model calculation The distinct electronic effects originating from the subtle changes of the substituents on the capping N-donor coligands induce varying coordination microenvironments and geometries on the Dy(III) sites, further drastically impacting the overall magnetic properties of the title complexes. The disparities of the uniaxial anisotropy and the magnetic dynamics for 1-5 have been elucidated by ab initio calculations as well.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic.

This work assessed solvent isotope effects on the photoracemization rate and emission lifetime for [Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) in water. An anal. of the effects of temperature on photoracemization rate and emission lifetime demonstrated that the transition from one enantiomer to the other is unaffected by the isotopic composition of the solvent. Also deactivation from the metal-to-ligand charge-transfer (3MLCT) excited state to the ground state is responsible for the solvent isotope effect on the photoracemization rate. The photoracemization reaction proceeds via a bond-breaking mechanism. In this process, a five-coordinated species produced through breaking of the Ru-N bond in the 3d-d* state undergoes a structural change to produce an achiral five-coordinated species. An anal. of the effect of temperature on emission lifetime, excluding the activation to the 3d-d* state that leads to the structural change, showed that the solvent isotopic composition affects deactivation from the 4th MLCT state.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ) is researched.Name: 5,5′-Dimethyl-2,2′-bipyridine.Kaur, Harpreet; Walia, Sidharth; Karmakar, Anirban; Krishnan, Venkata; Koner, Rik Rani published the article 《Water-stable Zn-based metal-organic framework with hydrophilic-hydrophobic surface for selective adsorption and sensitive detection of oxo-anions and pesticides in aqueous medium》 about this compound( cas:1762-34-1 ) in Journal of Environmental Chemical Engineering. Keywords: zinc metal organic framework hydrophilic hydrophobic oxoanion pesticide detection. Let’s learn more about this compound (cas:1762-34-1).

Given the importance of surface-functionalized materials with improved adsorption and detection properties for targeted applications, we report herein the design and development of a water-stable luminescent Zn-based metal-organic framework (Zn-MOF) with the hydrophobic-hydrophilic surface property. The developed luminescent Zn(II)-MOF {[Zn(PA2-)(dmbpy)](DMF)}n was synthesized via a solvothermal method using pamoic acid (PA) and 5,5′-dimethyl-2,2′-bipyridine (dmbpy) with free functional groups (hydroxyl and Me groups). Careful single-crystal structure anal. revealed a 3-dimensional hydrogen-bonded network with a one-dimensional channel and functionalized surface. The surface functionalization was achieved through rational choice of ligands bearing Me and hydroxyl groups as suitable hydrophobic and hydrophilic functionalities resp., leading to a stable MOF in the aqueous medium. The MOF was used as an adsorbent for selective adsorption of monovalent permanganate anion (MnO4-) over other polyvalent oxo-anions as well as an optical platform for the detection of oxo-anions (permanganate (MnO-4), dichromate (Cr2O72-) and chromate (CrO42-)) and pesticide (2,6-dichloro-4-nitroaniline (2,6-DCNA)) in the aqueous medium. Overall, a combination of luminescent nature and hydrophilic-hydrophobic surface property makes the developed Zn-MOF an interesting platform for environmental application.

Author is Kaczmarek, Anna M.; Van Der Voort, Pascal.

In this work authors introduce the use of nano-sized (50-70 nm) lanthanide-grafted periodic mesoporous organosilicas for both metal ion sensing and solvent sensing. For this study a PMO constructed from the N,N-bis(trimethoxysilylpropyl)-2,6-pyridine dicarboxamide linker and tetra-Et orthosilicate (at a 5 : 95 ratio) was employed. This material was grafted with Eu3+, Tb3+ or a mixture of Eu3+-Tb3+ chloride salts to obtain strongly emitting nano-sized luminescence materials. To further enhance the luminescence properties of the materials two different co-ligands were used – 1,10-phenanthroline (phen) and 5,5′-dimethyl-2,2′-dipyridyl (bpy). The luminescence properties of the developed series of hybrid materials were studied in detail in the solid-state and after dispersing in water. The materials were investigated for their use as ion sensors, with the Eu3+ and Tb3+ phen and bpy co-grafted materials showing selective “”turn on”” fluorescence for Pb2+ and Cr3+ ions (at a 10 ppm concentration of the ions). The Eu3+-Tb3+ co-grafted materials showed solvatochromism and could be used as a solvent sensor to distinguish between protic and aprotic solvents.

Formula: C12H12N2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Ru(II)/N-N/PPh3 complexes as potential anticancer agents against MDA-MB-231 cancer cells (N-N = diimine or diamine). Author is Ribeiro, Gabriel H.; Colina-Vegas, Legna; Clavijo, Juan C. T.; Ellena, Javier; Cominetti, Marcia R.; Batista, Alzir A..

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.
