✦ Synopsis

Photwxcitation of distance restricted triads consisting of zinc porphyrin (ZnP), free-base porphyrin (HP), and pyromellitimide (Im) at 532 urn in THF at room temperature led to long-lived charge separated states (ZnP)+-H2P-(Im)-with a lifetime of 0.16-80 ps via electron transfer from the ' (H2P)* to the Im followed by electron transfer from the ZnP to the (H,P)+. The lifetime of ( ZnP)+-H2P-( Im)-state is dependent upon distances between the charges and the stnxtures of linkage between the ZnP and HZP.

Upon photoexcitation of fixed-distance triads consisting of zinc-porphyrin (ZnP) or magnesium-porphyrin (MgP), a doubly strapped metal-free porphyrin (SH,P), and pyromellitimide (PIm), (ZnP) +-SH2P-(PIm)-and (MgP)+-SH2P-(PIm)-ion pair states are produced in high yields by two-step electron-transfer
