Supramolecular boosted superexchange

In this issue of Chem, Zhao et al. present a supramolecular strategy for controlling symmetry-breaking charge separation (SB-CS) through guest-mediated superexchange pathways. In a cyclophane host, guest molecules accelerate or suppress SB-CS by enhancing electron-transfer efficiency. This dynamic system enables tunable charge separation and demonstrates potential for photocatalysis, light energy conversion, and applications in organic photovoltaics.
