Monolithic multifunctional chromophores have been developed as a new class of organic photorefractive materials. Oligomeric carbazole molecular systems in the form of starburst dendrimers and conjugated trimers were studied. Molecular solids of acceptor-substituted carbazole oligomers and dendrimers exhibit glass transition. The second-order nonlinear optical coefficients d(ij) were determined to be 50 pm/V by second-harmonic generation measurements. We also examined the photoconductive properties by the xerographic discharge method. Two beam coupling and four-wave mixing experiments were performed to characterize photorefractivities, The photorefractive phase shift measurement indicated that the induced index grating is shifted by 90 degrees with respect to the absorption grating. Unlike usual photorefractive polymers containing multi-component systems these multifunctional chromophores can be applied to monolithic photorefractive materials.
