Synthesis And Electro-chemical Properties Of TTF Carboxylates Coordination Compounds

Since substantial applications have been reported in the field of material science and supramolecular chemistry, tetrathiafulvalene (TTF), included its derivatives, has been one of the most extensively studied molecules. In this work, a dicarboxylate of TTF was used for the study, and the major contents are as follows:In introduction, the properties and important achievements of TTF derivatives were reviewed briefly, the general aspect of supramolecular chemistry and the new progress in molecular recognition were described, and the different coordination modes of carboxyl groups were also summarized.In chapter 2, the TTF-dicarboxylate salt was regarded as an object for research. The electrochemical responses of the salt to H~+ cation and the mechanism of the equliblums have been discussed. This kind of molecules has potential applications in redox switch and chemical sensor.In chapter 3, a new supramolecular compound was obtained by reaction of the TTF sodium salt with benzotriazole. Its X-ray crystal structure has been determined and it is formed by the coordination of carboxylate with Na~+ ions and hydrogen bonds. The behaviors on molecular recognition have also been studied by spectra and electrochemistry.In chapter 4, two coordination compounds were obtained by reaction of ligand with nitrates of transition metals, Co(â…¡) and Ni(â…¡). Their crystal structures and properties were detailed studied. The carboxyl oxygen atoms can either coordinate directly to the metal atoms or combine by the protons in the hexaaquometal cations.
