We synthesized new liquid crystal compound, 4-n-alkylcyclohexylbenzyl 2'-perfluoropropoxy-2',3',3',3'-tetrafluoropropyl ether(ACPTE) and 4-n-alkylbicyclohexylbenzyl 2'-perfluoropropoxy-2',3',3',3'-tetrafluoropropyl ether(ABPTE), and investigated their liquid crystalline phase transition and electro-optical properties. ACPTE and ABPTE showed smectic A, B and E phases and both are found to act as one component lowering the refractive anisotropy in ZLI-1132 solvent.
