Mesomorphic and ion conducting properties of dialkyl(1,4-phenylene)diimidazolium salts

Abstract

A new family of dialkyl(1,4-phenylene)diimidazolium salts has been synthesized. Salts containing triflate and bis(trifluoromethanesulfonyl)imide anions and different alkyl chains have been prepared. The molecular structures of didodecyl(1,4-phenylene)diimidazolium triflate and bis(trifluoromethylsulfonyl)imide salts were determined by single crystal X-ray diffraction, and the mesomorphic and ionic conducting properties of all these compounds were investigated and are reported here.
