自2008年以来,可见光驱动的光催化反应成为有机化学和催化化学的研究热点之一。在众多的光催化反应中,主流的过渡金属光敏剂主要集中在以钌(II)和铱(III)为代表的贵重金属光催化剂上。但这类金属光催化剂存在中心金属储量少、价格昂贵及毒性较大等缺点。近年来,以丰产金属铜(I)为中心金属的光催化剂被不断开发并在光催化反应中获得逐步应用。特别地,基于P/N杂配Cu(I)光催化剂介导的光催化反应受到化学家的极大关注并且发展迅速。该类金属光催化剂具有中心金属储量丰富、价格低廉和毒性较低的优点,不仅可以替代钌(II)、铱(III)等贵重金属光催化剂催化常规的光催化反应,而且还能实现钌(II)、铱(III)等光催化剂所不能完成的光催化反应,对于高效构建有机分子多样性发挥了重要作用。本文根据反应机理的不同,从单电子转移、铜基光催化剂的双功能催化、双金属协同催化及能量转移四个类型出发,对P/N杂配Cu(I)光催化剂介导的光催化反应进展进行了综述。文末对该领域所存在的问题和局限性进行了总结, 并对今后的发展方向作了展望。

Visible-light-driven photocatalytic reactions have become one of hot research toptics in organic chemistry and catalytic chemistry since 2008. Among various photocatalytic reactions, the predominant tranistion-metal photocatalysts are those photosensitizers based on noble transition-metals, such as Ru(II) and Ir(III) as the central metal. However, this type of tranisition-metal photocatalysts has several drawbacks associated with their central metals including poor reserves in the earth, high prices and high toxicities. Recently, photocatalysts based on the earth-abundant copper(I) as the central metal have been continuously explored and gradually applied in photocatalytic reactions. In this regard, P/N-heteroleptic Cu(I)-photocatalyst-triggered photocatalytic reactions have specially received great attention and gained rapid development. Such Cu(I)-photocatalysts have advantages of abundant reserves, low prices and low toxicities related to their copper(I) central metal. These photocatalysts not only can replace Ru(II)- and Ir(III)-photocatalyts to trigger conventional photocatalytic reactions, but also can realize some photocatalytic reactions that are hard to be accomplished by Ru(II)- and Ir(III)-based photocatalysts, thus playing an important role in the highly efficient construction of molecular diversities. This article reviews the recent progresses in P/N-heteroleptic Cu(I)-photocatalyst-triggered visible-light-driven photocatalytic reactions according to four catagories of different reaction mechanisms, namely, single electron transfer (SET), bifunctional catalysis of Cu(I)-photocatalysts, copper/transition metal synergistic catalysis and energy transfer (ET). At the end of this review, the problems and limitations in this field are summarized, and the future reasearch direction of this field is also prospected.
