This review article deals with the use of gold metalloligands as building blocks for the assembly of heterometallic complexes. Several families of gold complexes decorated with crown-ether, amide, pyridine, bipyridine, terpyridine, carboxylato, amino acid or π-alkyne binding sites have been reported. Adducts of these metalloligands with alkaline or transition-metal cations, or with transition-metal or lanthanide complexes, have been isolated and structurally characterized. The reported heterometallic species range from simple dinuclear complexes to self-assembled supramolecules, coordination polymers, or solids. New structural motifs have been found in these complexes. Most of these metalloligands and complexes are photoluminescent and some of them show switchable emissions based on the formation and rupture of metallophilic contacts. Potential applications as sensors, sensitizers, in vivo imaging agents, and anticancer drugs are envisaged.
这篇综述文章论述了金金属配体作为构建异金属配合物的基本单元的应用。已报道了几类装饰有冠醚、酰胺、吡啶、联吡啶、三联吡啶、羧基、氨基酸或π-炔烃结合位点的金配合物。这些金属配体与碱金属或过渡金属阳离子，或与过渡金属或镧系配合物形成的加合物已被分离并进行了结构表征。报道的异金属物种范围从简单的双核配合物到自组装超分子、配位聚合物或固体。在这些配合物中发现了新的结构基序。这些金属配体和配合物大多具有光致发光性，其中一些基于亲金属接触的形成和断裂表现出可切换的发射。设想了其作为传感器、敏化剂、体内成像剂和抗癌药物的潜在应用。
