摘要：

Photoexcitation of distance restricted triads consisting of zinc porphyrin (ZnP), free-base porphyrin (H2P), and pyromellitimide (Im) at 532 nm in THF at room temperature led to long-lived charge separated states (ZnP)+-H2P-(Im)- with a lifetime of 0.16-80 mus via electron transfer from the 1(H2P)* to the Im followed by electron transfer from the ZnP to the (H2P)+. The lifetime of (ZnP)+-H2P-(Im)- state is dependent upon distances between the charges and the structures of linkage between the ZnP and H2P.
