摘要：

A multifunctional molecule that possesses photoconductive and electro-optic properties in one molecule was synthesized as a photorefractive organic glass. Diphenylhydrazone as a photoconductive moiety was covalently bound to the enamine derivative as an electro-optic chromophore via a flexible ester link. The sample prepared from a mixture of the multifunctional molecule (99 wt %) and fullerene C-60 (1 wt %) showed good photorefractive properties. The 100 mu m thick film showed a maximum diffraction efficiency of 69% at a low applied field of 25 V/mu m, corresponding to a refractive index modulation (Delta n) of 1.50x10(-3) and a photoconductivity of 0.46 pS/cm.
