Abstract

Abstract: Two kinds of novel photochromic composites—6-nitro-BIPS/graphene oxide and 6-nitro-BIPS/N719 were synthesized by esterification reaction. Spectroscopic characterization confirms 6-nitro-BIPS is covalently attached to graphene oxide and N719 through ester linkages. Compared with the individual components and the mechanical mixtures, 6-nitro-BIPS/graphene oxide and 6-nitro-BIPS/N719 show improved nonlinear optical properties at 532 nm in nanosecond region, resulting from the photoinduced electrons and/or energy transfer. Moreover, these two composites exibit photoswitchable nonlinear optical behavior, which are therefore promising candidates for use in optoelectronic and photonic devices.
