A novel liquid crystal compound with a carboxyl group at one end, cholest-5-en-3-ol-(3β) hydrogen decanedioate (1) was successfuly prepared by the reaction of cholesterol with sebacoyl chloride. Its chemical structure and liquid crystalline properties were characterized by FTIR, ¹³CNMR, ¹HNMR, POM and DSC. The compound with an active carboxyl group shows themortropic liquid crystalline behaviour.
