Selective excitation of charge-transfer (CT) complexes between acenaphthylene and various electron acceptors gives net reaction products when the resulting radical ion pairs lie at sufficiently higher energy than the ground state (large –ΔGBET); however, with decrease of –ΔGBET, these tend to become less reactive and finally non-reactive.
当
苊烯和各种电子受体之间的电荷转移(CT)复合物被选择性激发时,所产生的自由基离子对的能量比基态(大 -ΔGBET)高时,就会产生净反应产物;但是,随着 -ΔGBET 的降低,这些产物的反应性会减弱,最终失去反应性。
