Photoconductive property in the lyotropic liquid crystalline cell composed of hole transport molecules pendant poly(glutamate)

Hole transport molecules pendant polypeptide was synthesized in order to investigate the photoconductive property in the lyotoropic liquid crystalline polypeptide. By the application of an electric field to the liquid crystalline cell, the schlieren structure indicating the nematic structure was observed in the cell by using a polarized optical micrograph. Relatively high drift mobility of ca. 10−3 (cm2/V·s) and photoconductivity were obtained in the nematic liquid crystalline cell. Consequently, we conclude that highly ordered intra and interchain structure is effective for the photoconductive and charge carrier transport properties.
