A series of IPA were synthesized from single- and double-chain quaternary- ammonium surfactants as the cationic counterpart and dodecylbenzenesulfonate as the anionic counterpart by ion-exchange metathesis reaction. Their thermal as well as liquid crystalline properties were studied with respect to the change in alkyl chain length of the cationic counterpart by Thermo Gravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Hot-Stage Polarized Light Microscopy (HSPLM). They show high thermal stability and exist as Smectic liquid crystals at room temperature.
