The generation of long-lived charge transfer (CT) states in electron donor/acceptor dyads upon photoexcitation is crucial for artificial photosynthesis, photocatalysis and photovoltaics. Electron spin control is a novel strategy to prolong the CT state lifetime via generation of the CT triplet state, instead of the traditional short-lived CT state. This method involves a local triplet excited state (LE) as the precursor of charge separation (CS), and the electron forbidden feature of the charge recombination (CR) of CT → Svs. the electron spin allowed CT → S prolongs the CT state lifetime. In this article, we summarized the recent developments and challenges in this emerging fascinating area.
光激发时电子供体/受体二元体系中长寿命电荷转移（CT）态的产生对于人工光合作用、光催化和光伏技术至关重要。电子自旋控制是一种通过产生CT三重态来延长CT态寿命的新策略，而不是传统的短寿命CT态。该方法涉及将局域三重激发态（LE）作为电荷分离（CS）的前体，并且CT→S的电荷复合（CR）的电子禁阻特性与电子自旋允许的CT→S相比延长了CT态寿命。在本文中，我们总结了这个新兴迷人领域的最新进展和挑战。
