中文摘要	an ultrathin composite film containing both polyoxometalate anion [pmo12o40](3-) ( pmo12) and a planar binuclear phthalocyanine, bi-copc, has been prepared by the electrostatic layer-by-layer self-assembly method. uv-vis measurements revealed regular film growth with each four-layer {pmo12/bi-copc/pss/pah} adsorption. the lm structure was characterized by small-angle x-ray reflectivity measurements, x-ray photoelectron spectra, and afm images. the nanothick film shows a third-order nonlinear optical response of chi((3)) = 4.21 x 10(-12) esu. experimental investigations also indicate that the combination of polyoxometalate anions [pmo12o40](3-) with the phthalocyanine bi-copc in multilayer films can enhance the third-order nlo susceptibility and modify the third-order nlo absorption of bi-copc.
