Abstract

A series of LC polyesters containing banana-shaped mesogen and flexible spacer were synthesized. Their structures were identified by FT/IR- and NMR-spectrometry. Thermal and mesomorphic properties were investigated by using DSC and polarizing microsope. Structure of mesophase was investigated by using x-ray diffractimetry.
