Abstract
Polypeptide having carbazolyl groups (poly-gamma-[2-(9-carbazolyl) eth yl]-L-glutamate) (PCLG) was synthesized in order to prepare a lyotropi c liquid crystalline cell with higher mobility. Typical Time-Of-Flight (TOF) method was employed to analyze its charge transport property. T ransient photocurrent for the liquid crystalline cell showed nondisper sive transport property. Relatively high drift mobility of ca.10(-3) ( cm(2)/V.s) was obtained in the cell composed of PCLG with both intra a nd interchain ordered structure.
