LB films of five new hybrid polyvinylcarbazole/heteropolyanions PVK/BA/HPC (HPC = Na_5-[PZ(H_2O)Mo_(11)O_(39)]·5H_2O, Z = Mn, Co, Cu, Zn, Ni) were prepared and characterized by π-A isotherms, UV-vis absorption spectroscopy, low-angle X-ray diffraction (LAXRD), atomic force microscope (AFM), surface photovoltage spectroscopy (SPS) and fluorescence spectroscopy. The experimental results indicate that they have good film-forming property on the air-water interface. The collapse pressure of LB film is 22～27 mN/m. The lamellar structure obtained consists of monolayers of the heteropolyanions sandwiched between bilayers of the PVK macromolecule and BA. The fluorescence spectra shoed that strong emission of PVK appeared in the films. The title LB films also have stronger photoelectric response.
