Assembly And Property Of Tetrathiafulvalene Compound With Carboxylate Group

Tetrathiafulvalene(TTF)and their derivatives have been one kind of the most extensively studied functional molecules due to their potential application in the field of material chemistry and supramolecular chemistry.On the other hand,carboxylates have been used in analysis chemistry,enzyme and chemical catalysis,bionics chemistry,and material chemistry.In this thesis,we pay attention to the study of TTF-carboxylate derivatives,which integrate both the functional groups.The major contents we researched were as follows:1,In introduction,the properties and important achievements of TTF derivatives are reviewed briefly.Recent researches on TTF-carboxylates with redox groups are described,and the different coordination modes of carboxyl groups are also summarized.Then the new progresses in molecular recognition are summarized;2,In chapter 2,two TTF-dicarboxylate salts(Na,K)and their metal complexes with Ca(â…¡)and Co(â…¡)are synthesized.Structure of the Ca complex is determined by single crystal X-ray diffraction.The electrochemistry and UV spectra of the two complexes are also studied to understand the charge transfer between metal cation and TTF group;3,In chapter 3,the TTF-monoacid is synthesized,and the redox property of the acid is researched by UV-vis-NIR spectra and electrochemistry.The equilibriums of TTF-COOH with the added small molecules(nitrogen)are discussed;4,In chapter 4,the TTF-monocarboxylate is regarded as an object for research, and three new CT salt(C₂₀H₂₀S₁₂O₄Cu₂Cl₆,C₂₀H₂₀S₁₂O₄CuBr₄,C₂₀H₂₀S₁₂O₄Hg₂Cl₆) are synthesized.The structure of the compound(C₂₀H₂₀S₁₂O₄Cu₂Cl₆)has been determined by single crystal X-ray diffraction,and the UV spectra and electrochemistry of the compounds are discussed.
