Abstract

Abstract : Low molecular-mass organic compounds 1 and 2 having 2-(perfluoroalkyl)ethyl groups at both terminal positions were prepared and their gelation abilities were explored. Compounds 1 and 2 without hydrogen bonding group can gelatinize various organic solvents and/or ionic liquids at low concentration. Compound 1 can gelatinize toluene, while compound 2 dissolve in toluene. Compounds 1 and 2 gelatinize electrolyte showing effective gelation properties. The firmed supramolecular gels are physical gels with thermally reversible sol-gel phase transition. The difference of ionic conductivity between liquid state and gel state were analyzed.
