Category: benzodioxans. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Construction of lanthanide complexes supported by 2,3-dimethoxybenzoic acid and 5,5′-dimethyl-2,2′-bipyridine: crystal structures, thermoanalysis, magnetic and fluorescence properties.

A series of novel trivalent lanthanide complexes, [Ln(2,3-DMOBA)3(5,5′-DM-2,2′-bipy)]2·C2H5OH (Ln = Eu (1), Sm (2), Gd (3), Ho (4) Er (5), Pr (6), Nd (7)) (2,3-DMOBA = 2,3-dimethoxybenzoate, 5,5′-DM-2,2′-bipy = 5,5′-dimethyl-2,2′-bipyridine), have been successfully synthesized and structurally validated by single crystal diffraction. All complexes discussed herein feature a binuclear structure, and contain only one free ethanol mol., which is interesting in the lanthanide complexes. The coordination number of center Ln3+ ions is nine, showing a distorted monocapped square anti-prismatic coordination geometry. Through a pair of alternating identical C-H···O hydrogen bonding interactions between two 2,3-DMOBA ligands on the same lanthanum binuclear unit with 5,5′-DM-2,2′-bipy ligands on two neighboring units, the binuclear complexes can form one- The thermal anal. of these complexes are investigated by TG-DSC/FTIR, the result show that the decomposition process of complexes are mainly divided into four stages with the formation of the resp. oxides. The visible light emission experiment of complex 1 is carried out, and the characteristic luminescence behavior of intense red light is exhibited. What’more, fluorescence lifetimes as well as the fluorescent quantum yield of complex 1 is calculated And the magnetic properties of complexes 3-5 are also studied.
There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(C=C1)C1=NC=C(C)C=C1)Category: benzodioxans, and with the development of science, more effects of this compound(1762-34-1) can be discovered.
