中文摘要a novel multifunctional inorganic-organic photorefractive (pr) poly(n-vinyl)-3-[p-nitrophenylazolcarbazolyl-cds nanocomposites with different molar ratios of us to poly(n-vinyl)-3-[p-nitrophenylazo]carbazolyl (pvnpak) were synthesized via a postazo-coupling reaction and chemically hybridized approach, respectively. the nanocomposites are highly soluble and could be obtained as film-forming materials with appreciably high molecular weights and low glass transition temperature (t,) due to the flexible spacers. the pvnpak matrix possesses a highest-occupied molecular orbital value of about -5.36 ev determined from cyclic voltammetry. second harmonic generation (shg) could be observed in pvnpak film without any poling procedure and 4.7 pm/v of effective second-order nonlinear optical susceptibility is obtained. the us particles as photosensitizers had a nanoscale size in pvnpak adopting transmission electron microscopy. the improvement of interface quality between us and polymer matrix is responsible for efficient photoinduced charge generation efficiency in the nanocomposites. an asymmetric optical energy exchange between two beams on the polymer composites pvnpak-cds/ecz has been found even without an external field in two-beam coupling (tbc) experiment, and the tbc gain and diffraction efficiency of 14.26 cm(-1) and 3.4% for pvnpak-5-cds/ecz, 16.43 cm(-1) and 4.4% for pvnpak-15-cds/ecz were measured at a 647.1 nm wavelength, respectively.
