Liquid crystalline 2-thienyl-4,6-diamino-1,3,5-triazines exhibiting Imm and Pmn micellar cubic phases in an inverted sequence†
Abstract
Two micellar cubic phases with different structures were observed for the first time in the order Imm–Pmn in a thermotropic phase sequence of 4,6-diaminotriazine terminated rod-like liquid crystals upon increasing alkyl chain length or rising temperature.
