Synthesis and Physical Properties of Organogels based on Low Molecular Weight Gelators: 4-(2-Perfluoroalkyl)ethylthiobenezene Derivatives

摘要

Several derivatives for 4-(2-perfluoroalkyl)ethylthiobenzene were prepared and their gelation properties were investigated. The alkyl and alkylene derivatives formed organogels with polar and non-polar organic solvents such as alcohols, tolunene, N,N-dimethylformamide, acetonitrile and propylenecarbonate. The thermal properties for these organogels are revealed to be thermo-reversible physical gels. Furthermore, organogel electrolyte using alkyl derivative was prepared from LiPF_6 as a supporting electrolyte and mixed solvent of ethylene carbonate and dimethyl carbonate, and the ionic conductivities of gel electrolyte and that of the corresponding electrolyte solution were examined.
