4,4'-Bis(stearoylamino)diphenyl ether (BSDE) as a gelator self-assembled into elongated fibril aggregates by non-covalent interaction in aqueous and organic media, such as water, DMF, DMSO, propylene carbonate (PC) etc., and also their solutions containing lithium salts.These fibril aggregates are able to aggregate futher into three-dimensional networks, causing medium gelation so-called molecular gel.A novel gel electrolyte was prepared by the gelation of above solutions containing lithium salts.The ionic conductivity is in the range of 10^-1～10^-2 S·cm^-1 for water molecular gel and 10^-2～10^-3 S·cm^-1 for PC molecular gel at room temperature.The results indicate that the behavior of supporting electrolytes in the gels is essentially similar to that in the isotropic solution.At -35℃, the ionic conductivity of the gel is only 1～2 magnitudes lower than that of related solutions.
