A small library of dinuclear gold(I) complexes with the title ligands has been prepared, encompassing neutral, mono- and dicationic complexes. The luminescence properties of the complexes in the solid state have been evaluated, and it turns out that neutral and monocationic complexes not presenting a rigid metallamacrocyclic structure can exhibit rather strong emissions that extend towards the red region of the visible spectrum. The in vitro anticancer activity of the complexes has been also preliminarly evaluated; cytotoxicity seems to correlate with complex lipophilicity, whereas selectivity towards cancer cells can be apparently enhanced upon a judicious choice of the ligands.

与 N-膦基、N-杂环卡宾配体的双核金 (I) 配合物：合成策略、发光特性和抗癌活性

已经制备了带有标题配体的双核金 ( I ) 配合物的小型文库，包括中性、单和双阳离子配合物。已经评估了固态配合物的发光特性，结果表明，不呈现刚性金属大环结构的中性和单阳离子配合物可以表现出相当强的发射，向可见光谱的红色区域延伸。复合物的体外抗癌活性也已初步评估；细胞毒性似乎与复杂的亲脂性相关，而对癌细胞的选择性可以通过明智地选择配体而明显增强。
