摘　　要：The amphiphilic porphyrin, 5, 10, 15, 20-tetra-(4-hexadecylpyridiniumyl) porphyrin bromide (TC 16PyP), has good film-forming property on the air/water interface. The structure of TC 16PyP Langmuir-Blodgett films was characterized by UV-Vis absorption spectra, fluorescence spectra and low-angle X-ray diffraction (LAXD). It is indicated that TC 16PyP LB films have good stability and structure homogeneity. The photoelectric behavior of electrochemical cell of TC 16PyP LB films deposited on SnO 2 optically transparent electrodes (SnO 2 OTE) were investigated by using the system of bicell and bielectrode. The experimental results show that the photocell can generate large and stable photocurrent and photovoltage, the photoelectric device made from TC 16PyP LB films has a potential application value.The amphiphilic porphyrin, 5, 10, 15, 20-tetra-(4-hexadecylpyridiniumyl) porphyrin bromide (TC16PyP), has good film-forming property on the air/water interface.
