摘要：

Long live the state! Photoexcitation of a zinc chlorin-fullerene dyad with a short linkage results in the formation of the ultra-long-lived charge-separated (CS) state by a one-step photoinduced electron transfer without loss of energy, which is inevitable for charge separation by multistep electron-transfer processes. The lifetime of the charge-separated state was 120 s in frozen PhCN at -150°C (see picture).
