Carbazole-containing compounds, such as poly-(vinylcarbazole), have considerable interests in their characteristic photoelectric properties. In this work, we have synthesized two types of liquid crystalline copolymers containing carbazole moiety in the side chain in order to clarify the influence on the orientational behavior to the photoelectric properties. Copolymers were prepared by conventional AIBN-initiated free-radical addition-polymerization of methacrylate monomers. Thermal properties of these copolymers were examined by differential scanning calorimetry and thermal optical polarized microseopy, and fluorescent characteristics were also measured.The copolymers exhibited nematic phase above 60mol% of the mesogaenie monomer content. Fluorescent spectroscopy showed that the peak intensity of emissican spectroscopy in the copolymers decreased remarkably after annealing.
