Abstract

Photorefractive (PR) responses for guest-host polymers containing a liquid carbazole which shows hole transport properties are presented. We measured the two-beam coupling (TBC) gain for the PR polymers containing a host polymer polyvinylcarbazole (PVK), the liquid 9-(2-ethylhexyl)carbazole (EHCz), an electro-optic chromophore 4-piperidinobenzylidene malonitrile (PDCST), and a sensitizer C60 with different mixture ratios of PVK and EHCz. We also measured the trap density for those PR polymers by the phase shift measurement in the TBC technique. These experiments show that the liquid carbazole control the trap density as well as the PR responses.
