Self-assembly Chemistry And Magnetic Based On Asymmetric Ligands Containing Oxadiazoles With Quinolinyl Groups And Their Thione Derivatives

In recent years,organic-inorganic coordination compounds driven by coordination have been one of the hot topics for chemists.They are used in many research fields due to their complex and diverse structure and excellent physicochemical properties.This article describes a series of symmetric and asymmetrical organic ligands base on quinolyl-1,3,4-oxadiazole.And through the self-assembly method with transition metal we obtain a variety of new coordination compounds.In addition,we characterized the structures and properties by X-ray single crystal diffraction,infrared spectroscopy,fluorescence,thermogravimetric analysis and so on.1.First,two novel 1,3,4-oxadiazole-2-thione ligand were designed and synthesized,and several new coordination compounds were obtained with the transition metal.Among them,a novel metal-organic cages was obtained.2.Second,symmetric and asymmetric 1,3,4-oxadiazole ligands with quinoline groups as the end groups were designed and synthesized.At the same time,pyridine rings,imidazole rings,etc.were introduced into the ligands.Several kinds of new coordination compounds were obtained with transition metal.The structures were characterized and a series of physicochemical properties were determined.3.Third,we conducted magnetic studies on coordination compounds containing asymmetric semi-rigid 1,2,4-triazole ligands.
