A supramolecular naphthalenediimide radical anion was developed through host-guest interactions between NDI and cucurbit[7]uril (CB[7]), which can be greatly promoted in the presence of chloride ions to obtain Cl˙ and NDI-2CB[7]˙. Under the synergistic action of Cl˙ as a hydrogen atom transfer (HAT) agent and NDI-2CB[7]˙ transferring electrons to O to produce O˙, the photocatalytic oxidation reactions of alkylarenes to carbonyls can be realized with universal applicability.
通过萘二亚胺（NDI）与葫芦[7]脲（CB[7]）之间的主客体相互作用，构建了一种超分子萘二亚胺自由基阴离子，在氯离子存在下，这种相互作用可大大增强，从而得到Cl˙和NDI-2CB[7]˙。在作为氢原子转移（HAT）剂的Cl˙与NDI-2CB[7]˙将电子转移给O以生成O˙的协同作用下，可实现烷基芳烃到羰基的光催化氧化反应，且具有广泛的适用性。
