摘      要：The synthesis and mesomorphic properties of a new class of liquid crystalline cyclotriphosphazenes with rigid cyanostilbene groups and flexible alkoxy groups are *** thermal behaviors of cyclotriphosphazene derivatives 5a-5d are studied by the means of differential scanning calorimetry,polarizing optical *** phases were observed in compounds 5a-5d both on heating and *** clear temperatures of compounds 5a-5d slightly increased with increasing length of terminal alkyl *** 5a-5d showed different mesogenic region from minimum 5℃to maximum 142℃.
