摘要：

Two new triad model compounds of porphyrin-viologen-carbazole (1a and 1b) with different chain length were synthesized to mimic photosynthesis. The absorption and fluorescence spectra in solution, in micelle solution as well as in binary solvent, were investigated; especially, the effects of aggregation on the photophysical properties were investigated. A mechanism including photoinduced electron transfer and two-step charge separation was suggested. These triad compounds were easily formed LB films. Rather high photodriven voltages and currents were obtained with only one monolayer of LB film on the surface of SnO2 conductive glass.
