Production of an Ultra‐Long‐Lived Charge‐Separated State in a Zinc Chlorin–C₆₀ Dyad by One‐Step Photoinduced Electron Transfer

Abstract

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).
