Simple exploration of 1762-34-1

Compound(1762-34-1)Safety of 5,5′-Dimethyl-2,2′-bipyridine received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(5,5′-Dimethyl-2,2′-bipyridine), if you are interested, you can check out my other related articles.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, Article, Dalton Transactions called A sensitive photoluminescent chemosensor for cyanide in water based on a zinc coordination polymer bearing ditert-butyl-bipyridine, Author is Rosales-Vazquez, Luis D.; Valdes-Garcia, Josue; Bazany-Rodriguez, Ivan J.; German-Acacio, Juan M.; Martinez-Otero, Diego; Vilchis-Nestor, Alfredo R.; Morales-Luckie, Raul; Sanchez-Mendieta, Victor; Dorazco-Gonzalez, Alejandro, the main research direction is photoluminescent chemosensor cyanide zinc coordination polymer ditert butyl bipyridine.Safety of 5,5′-Dimethyl-2,2′-bipyridine.

Sensitive and direct sensing of cyanide in buffered aqueous solutions at pH = 7.0 by three new blue photoluminescent zinc-1,4-cyclohexanedicarboxylato coordination polymers bearing di-alkyl-2,2′-bipyridines has been achieved. Specifically, a Zn-polymer with the general formula: {[Zn2(H2O)2(e,a-cis-1,4-chdc)2(4,4′-dtbb)2]·7H2O}n, (1,4-chdc = 1,4-cyclohexanedicarboxylato and 4,4′-dtbb = 4,4′-ditert-butyl-2,2′-bipyridine) has been synthesized in high yield and studied as a luminescent chemosensor for halides, pseudohalides and a series of oxyanions in neutral water. CN- ions can be quant. detected by this polymer based on complete quenching (λem = 434 nm) in the sub-micromolar concentration range with a pronounced selectivity over common anions such as acetate, bromide and iodide. The quenching response (KSV = 9.7(±0.2) × 104 M-1) by the addition of CN- was also observed in the presence of typical interfering anions with a very low detection limit of 0.9μmol L-1 in buffered water at pH = 7.0. On the basis of the crystal structure and solid state CPMAS 13C-NMR correlation and 1H NMR, IR-ATR, MS-ESI(+) and SEM-EDS experiments, the optical change is attributed to the efficient release of its corresponding ditert-butyl-bipyridine, with the simultaneous formation of a zinc cyanide complex. The CPMAS 13C-NMR spectrum of the coordination polymer is consistent with the symmetry of the crystal structure. The use of flexible coordination polymers as fluorescent sensors for fast and selective detection of cyanide ions in pure aqueous solutions has been unexplored until now.

Introduction of a new synthetic route about 1762-34-1

Compound(1762-34-1)Formula: C12H12N2 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(5,5′-Dimethyl-2,2′-bipyridine), if you are interested, you can check out my other related articles.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called A series of lanthanide complexes with 2-fluorobenzoic acid and 5,5′-dimethyl-2,2′-bipyridine: Synthesis, supramolecular structures, spectroscopy and thermal behaviour, published in 2021-08-31, which mentions a compound: 1762-34-1, mainly applied to lanthanide fluorobenzoate dimethylbipyridine supramol preparation crystal mol structure stability; thermal stability fluorescence lanthanide fluorobenzoate dimethylbipyridine supramol complex, Formula: C12H12N2.

A family of lanthanide-based self-assembling complexes constructed from 2-fluorobenzoic acid and 5,5′-dimethyl-2,2′-bipyridine have been successfully fabricated via conventional synthesis, namely, [Ln(2-FBA)3(5,5′-DM-2,2′-bipy)]2 (2-FBA = 2-fluorobenzoate, 5,5′-DM-2,2′-bipy = 5,5′-dimethyl-2,2′-bipyridine, Ln = La (1), Pr (2), Nd (3), Sm (4), Gd (5), Dy (6), Ho (7), Er (8)). The obtained complexes are investigated by elemental anal., IR spectra, Raman spectra and single-crystal x-ray diffraction. Crystallog. results exhibit that each Ln3+ ion of them is located in a distorted Muffin coordination sphere finished by seven oxygen atoms of 2-FBA ligands and two nitrogen atoms of 5,5′-DM-2,2′-bipy ligand. Interestingly, although complexes 1-6 and 7-8 have the same formula unit, the differences in hydrogen bond interactions lead to different supramol. structures. Besides, the thermal decomposition mechanism of the complexes has been studied by TG/DSC-FTIR technol. The results show that these complexes are thermally stable up to 450 K. In addition, complexes 4 and 6 both exhibit the characteristic fluorescence of lanthanide ions, i.e., complex 4 exhibits characteristic 4G5/2→6HJ/2 (J = 5, 7, 9) transitions, and complex 6 shows characteristic 4F9/2→6HJ/2 (J = 15, 13) transitions.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Inorganic Biochemistry called 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 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.COA of Formula: C12H12N2.

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 understanding and the application of reversible covalent reactions and coordination chem. together with the proper design of the mol. frameworks, allow to achieve not only well-defined output architectures but also different grades of complex behavior. In this work, the dynamic nature of the helical systems offers an addnl. level of complexity by combining self-sorting on two levels: (1) the build-up of the ligand strand constituents from their components through dynamic covalent chem.; (2) the assembly of the helicates from the ligands and the metal cations through dynamic metallo-supramol. chem. The information encoded in the ligands constituent mol. was read differently (and accurately at the same time) by metal cations that varied in the coordination algorithms. It enabled the selective formation of a specific type of helicates from a wide library of helicates formed by the possible combination of subcomponents. Ligands containing dynamic tridentate and/or bidentate binding motifs in the same strand were studied to explore the helicates self-assembly with appropriate metal cations.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Thermodynamics of the Adsorption of Isomeric Dipyridyls and Their Derivatives from Water-Organic Solutions on HYPERCARB Porous Graphitic Carbon, published in 2019-09-30, which mentions a compound: 1762-34-1, Name is 5,5′-Dimethyl-2,2′-bipyridine, Molecular C12H12N2, HPLC of Formula: 1762-34-1.

High-performance liquid chromatog. is used under near-equilibrium conditions to study the adsorption of isomeric dipyridyls and their derivatives from water-acetonitrile, water-methanol, and water-isopropanol solutions onto Hypercarb graphite-like carbon material in the region of Henry’s law. It is shown that the possibility of forming strong intramol. C-H-N’-hydrogen bonds in a mol. of 2,2′-dipyridyl or its derivatives strengthens the adsorption bonding of adsorbate mols. and the surface of the graphite-like material due to stabilization of their planar conformation. Destabilizing this intramol. hydrogen bond by adding substituents in different positions of the pyridine rings enhances the specific intermol. interaction between adsorbate mols. and the solvent’s components and distorts the planar conformation of dipyridyls, weakening their retention on the Hypercarb material. Pos. adsorption from the water-organic medium on the carbon adsorbent is observed for all of the investigated dipyridyls, with the exception of 2,2′-dipyridyl-N,N’-dioxide, which is adsorbed weaker than the solvent components. Anomalous medium-property dependences are found for the thermodn. characteristics of the adsorption of dipyridyls on porous graphitic carbon, and are attributed to the predominance of adsorbate-adsorbent π-π interactions over hydrophobic ones and the resolvation of adsorbate mols. with acetonitrile in proportion to lowering the content of water in the bulk solution
