Synthesize And Characterize Conjugate Sulfur-rich Compound With Pyridine Group

Tetrathiafulvalene (TTF) and dithiolene derivatives have been widely studied in the research fields of material chemistry and supramolecular chemistry, because they exhibit optical, electronic and magnetic properties. Great interest is currently devoted to obtain organic/inorganic hybrid materials that combine the sulfur-rich organic donors with the transition-metal ions. In this work new TTF and dithiolene derivatives, which directly conjugated with pyridine group and have both redox property and metal coordination property, were synthesized and characterized. The major studies are as follows:1,In introduction, the properties and important achievements of TTF derivatives are reviewed briefly. Recent researches on TTF-Py with redox properties are summarized. At the same time, the dithiolene derivatives are described, Then the new progresses of d8 metal dithiolenes are summarized.2,New compound 2,3-dimethylthio-6-pyridyl-tetrathiafulvalene, DMT-TTF-Py, has been synthesized for research. Electrochemical responses of the compound to H+ cation and the corresponding UV-vis-NIR spectra have been studied. Crystal of two protonated salts were prepared. Structures of the them have been determined by single crystal X-ray diffraction.3,Three metal complexes of 4-pyridin-4-yl-(1,3) dithiol-2-one, PYDO have been designed and synthesized. The structures of these complexes have been characterized by single crystal X-ray diffraction. The coordination behaviors of the ligand and the intermolecular interactions of the compounds have been studied.4,A nickel dithiolene complex of PYDO have been synthesized and characterized. Electrochemical responses of the compound to H+ cation and the corresponding UV-vis-NIR spectra have been studied. Their redox and coordination behaviors were also studied by electrochemical and spectral analysis. The structures of two protonated compounds have been determined by single crystal X-ray diffraction.
