As reported recently in Nature Chemistry, Rumbles, Reid, and collaborators employed time-resolved dielectric-loss spectroscopy to probe the effect of counterions on the excited-state relaxation kinetics and charge-transfer selectivity of a cationic photoredox catalyst. This ion-pairing phenomenon can be used to control excited-state electron transfer and affect the branching points of photoredox mechanisms.

光氧化还原化学中的离子对效应

正如最近在Nature Chemistry上报道的那样，Rumbles、Reid 和合作者使用时间分辨介电损耗光谱来探测反离子对阳离子光氧化还原催化剂的激发态弛豫动力学和电荷转移选择性的影响。这种离子对现象可用于控制激发态电子转移并影响光氧化还原机制的分支点。
