A series of wedge-shaped acrylated sulfonate molecules with different counterions of Li, Na, K and Cs were synthesized. It has been proved that Na and K salts formed Colhd mesophases, while Li and Cs were at isotropic states by combintaion of DSC, polarizing microscopy and SAXS. The ion conductivity was then determined by impedance spectra using alternative circuits. The conductivity results demonstrated that the formation of a columnar mesostructure of Na and K salts has a much higher increase influence on the ion conductivity in comparison to Li and Cs salts which was at isotropic state, which indicated the great influence of columnar structures on ion conductivites.
