摘　　要：含氮杂环硫醇一价铜Cu(I)配合物不仅具有新颖多样的结构,而且在半导体材料、荧光、生物医药等方面表现出广阔的应用前景。这类配合物具有可见光吸收、荧光寿命长等特点,是潜在的光敏剂。以含氮杂环硫醇Cu(I)化合物作为光催化剂,在可见光诱导下,可以实现羰基化合物的还原或者还原自偶联反应,高产率地得到一系列一级醇、二级醇和频哪醇,并实现了α,β-不饱和羰基化合物的选择性氢化反应制备不饱和醇。Copper N-heterocycle thiolate clusters have attracted much interest due to not only their diverse structures,but also their potential applications in semiconductor materials,fluorescence,biological activity.These complexes are also promising candidates as visible-light-responsive photocatalysts owing to their strong absorption in the visible region and long fluorescent lifetime.Cu(I)N-heterocycle thiolate clusters are used as photocatalysts for efficient and convenient visible-light-activated reduction or reductive homocoupling of aldehydes or ketones,affording a series of primary alcohols,secondary alcohols and piancol compounds.These clusters also efficiently photocatalyze chemoselective reduction ofα,β-unsaturated carbonyls to yield unsaturated alcohols.
