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.
