英文摘要Photoinduced electron transfer (ET) between C-60 and porphyrin (P) in a new polymer containing porphyrin, poly(p- phenyle-nevinylene), and pendant fullerene units has been investigated by nanosecond transient absorption and phosphorescence spectroscopy. Compared to the physically doping material systems, binding porphyrin/C-60 through chemical bonds in a polymer detains the formation of the triplet states of porphyrins and C-60. The formation of intermediate charge transfer state (CSS) of P center dot+-C-60(center dot-) was observed, which led to the delayed formation of triplet states of porphyrins and C-60. The reduced opto-electronic properties, such as optical limiting performance, were also observed, which resulted from the delayed formation of triplet states. The results presented in this article are significant in understanding the complicated spectral characteristics of the triplet state and charge transfer of the porphyrin and C-60 complexes, and are therefore related to the controllable performance of the new materials in applications.
