Synthesis And Propertiesof Organic Gelators Based On Tetrathiafulvalene

Organic gelators can self-assemble into fiber, ribbon or linear through non-covalent bonding in an organic solvent. And further crosslinked to form a three dimensional network structure, So that the organic solvent is gelled. Due to the nature of the molecular structure, Assembled to form a structure and dimensions are not the same. Therefore, Functional organogel with special structures can be constructed by introducing some functional groups to the organogelators.Designing and synthesizing organic gelators with based on tetrathiafulvalene with cholesterol unit and L-glutamate unit is the main work in this thesis. The ability of the synthesized compouds forming organogel in different organic solvents is investigated. Their molecular structures are characterized by1H-NMR,13C-NMR, FT-IR and MALDI-TOF-MS.The ability of target compouds(12a-12f) forming organogel was studied. It is shown that the compoud12e can form chartreuse transparent-organogel in carbon tetrachloride,regulate the behavior of the gel by chemical oxidation, The UV-Vis spectra of the target compouds(12e) show that this molecule can accumulate in carbon tetrachloride solvents, The electrochemical properties of16a-c were measued by cyclic voltmmetric experiment, and their oxidation-reduction activity has been studied. The results revealed that all processes are quasi-reversible in terms of△E. Compounds22a and22e can form organogel in variety of organic solvents, such as chloroform, dichloromethane,1,2-dichloroethane. Regulate the behavior of the gel by chemical oxidation.The electrochemical properties of22a-22b were measued by cyclic voltmmetric experiment, and their oxidation-reduction activity has been studied. The results revealed that all processes are quasi-reversible in terms of AE.
