Misleading effects of impurities derived from the extremely long-lived electron-transfer state of 9-mesityl-10-methylacridinium ion

摘要

9-Mesityl-10-methylacridinium ion has an extremely long-lived electron-transfer state,which results in the misleading effects of electron donor impurities contained in benzonitrile to produce the stable acridinyl radical.Extensive efforts have been devoted to mimic the photosynthetic reaction center,leading to development of artificial systems which exceed both the lifetime and energy of the CS state of the natural system.
