摘要：

A new artificial photosynthesis porphyrin tetrad compound of porphyrin-terephthalic acid ester-viologen-carbarzole (1) was synthesized and compared with two triad compounds (2a, 2b) and two diad compounds (3a, 3b) for photoelectric conversion. The absorption and fluorescence spectra in solution and in binary solvent were investigated; especially the effects of aggregation on the photophysical properties were studied. A mechanism including photoinduced electron transfer and multistep charge separation for tetrad compound was suggested. By using the LB technique, the synthetic molecular devices were prepared with molecules 1, 2a, 2b, 3a, 3b and the model compound of porphyrin (4b), respectively. With only one monolayer of tetrad LB film on the surface of SnO2 conductive glass, rather high photodriven voltage and current were obtained.
