摘要：

Bifunctional molecule which possesses photoconductive and electrooptic properties in one molecule was synthesized as a new photorefractive material Carbazole as a photoconductive moiety was covalently bound to thiophene derivative as an electrooptic chromophore via a flexible alkyl chain The sample prepared from the mixture of bifunctional molecule (89 wt %) 2 4 7 trinitro 9 fluorenone (1 wt %) and ethylcarbazole (10 wt %) showed good photorefractive property The 50 mum thick film showed the maximum diffraction efficiency of 65% at 70 V/mum corresponding to a refractive index modulation (Deltan) of ca 4 5 x 10(-3) (C) 2002 Elsevier Science B.V.
