Abstract

Photocarrier generation properties and an electro-optic response were studied in acceptor-substituted carbazole materials. Two kinds of carbazole systems were investigated: molecularly doped polymer and main-chain polymer. The photoconductive sensitivity of 1.2x1012(S cm1)I(W cm2) was obtained with a field strength of 5x1O5V/cm at a wavelength of 534nm. The electro-optic coefficient 33 of l.lpmJV was obtained with a field strength of 5x1O5V/cm at a wavelength of 532nm. These results show the monolithic photorefractive polymer could be developed by using acceptor-substituted carbazoles.
