Abstract

We have developed a new multifunctional molecular glassy material, 2-(10-{6-[3-(diphenyl-hydrazonomethyl)-phenothiazin-10-yl]-hexyl} -10H-phenothiazin-3-yl-methylene)-malononitrile, with the a unique charge transport phenomena and large photoactive property for photorefractive applications. The photorefractive sample with a mixture of 2-[10-(2-ethylhexyl)- 10H-phenothiazin-3-yl-methylene]-malononitrile(PM-1) and N′-[10- (1-(ethyl-heptyl)-10H-phenothiazin-3-ylmethylene)-N,N-diphenyl-hydrazine(PH-1) showed a complementary grating behavior which could be explained by using the bipolar transport model. The transition from a bipolar transport phenomenon to a monopolar transport phenomenon was observed in the photorefractive composite bearing 2-(10-{6-[3-(diphenyl-hydrazonomethyl)-phenothiazin-10-yl]-hexyl}-10H- phenothiazin-3-yl-methylene)-malononitrile.
