Description
Summary:Photoconductivity measurements on stable photocrosslinkable nonlinear optical polymer - PVCN (polyvinylcinnamate)/CNNB-R (3-cinnamoyloxy-4-4-(N,N- diethylamino)-2-cinnamoyloxy phenvlazo nitrobenzene) are reported. Photoconductivity in this polymer system, in both crosslinked and uncrosslinked states, was observed without introducing any sensitizer or carrier-transport agents. Absorption of CNNB-R ( lambda peak = 518 nm) results in photocarrier generation and it is conjectured that CNNB-R also plays a role in the carrier transport. Such polymers are candidate materials for photorefraction.
