✦ Synopsis
The temperature dependence of the charge-recombination rate in photochemically generated ion-pair states (carotenoid, C)+-(porphyrin, P)-(pyromellitimide, Im)-has been shown to vary with a spacer between C and P. The triad with a 1,4-phenylene spacer exhibits only weak temperature dependence, while triads with methylene-bis_(l,4-phenylene) and benzanilide spacers exhibit distinct biphasic temperature dependence.

## Abstract As an excellent artificial photosynthetic reaction center, the carotene (C)‐porphyrin (P)‐fullerene (F) triad was extensively investigated experimentally. To reveal the mechanism of the intramolecular charge transfer (ICT) on the mimic of photosynthetic solar energy conversion (such as
