Synthesize And Characterize Conjugate Sulfur-rich Compound With Pyridine Group

Tetrathiafulvalene (TTF) 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 obtaining 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 conjugate 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 redox active TTF-Py compounds are summarized.2,New compound 2,6-bis(4-pyridyl)-1,4,5,8-tetrathiafulvalene (Py-TTF-Py), was synthesized for research. Electrochemical response of the compound to H+cation and the corresponding UV-vis spectra were studied. Crystals of two protonated salts were prepared and their structures were determined by single crystal X-ray analysis.3,Three metal complexes of 4'-pyridyl-4-yl-(1,3-dithiol)-2-one (PYDO) and Py-TTF-Py were synthesized. The structures and the intermolecular interactions of these complexes were characterized by single crystal X-ray analysis. The Cu(I) compound of Py-TTF-Py showed a novel 2-D structure. Electrochemistry and UV-vis spectra of the compounds were also studied.
