Synthesis and characterization of tin-organic liquid crystalline side group polyesters with mesogenic nitroazobenzene units

摘要

Three tin-containing nitroazopolymers with a tin-organic unit were synthesized and characterized by DSC, polarization microscopy, AFM and dielectric measurements. Dielectric measurements prove the existence of three relaxation ranges. No Vogel-Fulcher behaviour of the relaxation times were found. At low temperatures only different solid phases and no liquid crystalline exist.
