摘要
A new class of lambda-shaped azo materials with a cinnamate linkage group has been designed, synthesized, and well-characterized. Further, the liquid crystalline property has been studied by using POM and DSC analysis. Out of six derivatives, five compounds displayed liquid crystalline properties. The liquid crystalline property is observed in an enantiotropic manner. The structure-property relationship is further studied for the understanding of the exhibition of liquid crystalline properties. The results showed that their liquid crystalline phase behavior was closely related to the number of mesogenic units, rigidity, and flexibility of the molecular systems.
