Liquid crystalline (LC) poly(isothianaphthene methine)s have synthesized by introducing phenylcyclohexyl type LC groups into methine moieties as side chains. The polymers were characterized by IR, UV-Vis-nearlR, ¹H- and ¹³C-NMR spectroscopies. All polymers were soluble in common organic solvents and they showed bandgaps of 1.2 〜 1.3 eV. Electrical conductivities of 10^-4 - 10^-5 S/cm were obtained upon iodine doping. Some of the polymers were confirmed to have mesophase through DSC and POM measurements.
