Polycarbazole Showing Fingerprint Structure
Keywords:
Polycarbazole, liquid crystal, electrochemical polymerization
Abstract
Electrochemical polymerization of carbazole was carried out in cholesteric liquid crystal. Polarizing optical microscopy observation of the polymer film thus obtained shows fingerprint texture resembling with cholesteric liquid crystal electrolyte solution. The POM observations revealed that transcription of helical structure of cholesteric liquid crystal to the polymer was occurred. Furthermore, circular dichroism optical absorption spectrum shows that the polycarbazole prepared in cholesteric liquid crystal has optical activity.
