Abstract

A through-space superexchange mechanism appears to be responsible for charge recombination (CR) following photoexcitation and charge separation (CS) in rotaxanes containing zinc porphyrin and C60 moieties (see picture), as suggested by the low activation energy of this process. Furthermore, the charge-separated state is relatively long-lived.
