Abstract

Two dicationic salts with bis(triflimide) as counterions exhibited crystal-to-smectic liquid crystalline phase transitions (T_m=41 and 37°C) and smectic-to-isotropic liquid phase transitions (T_i = 112, 136°C). They had a broad liquid crystalline phase range (71-99°C) and an excellent range of thermal stability (360-364°C). Their mixtures of various compositions also displayed liquid crystalline properties from r.t. to an extended range of temperatures. They exhibited fluorescence in 1, 2-dimethoxyethane and methanol.
