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
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。

Dinuclear silver(I) complexes with bridging N-phosphorylated azolylidene ligands have been synthesized. Subsequent transfer of the ligands to other group 11 metal centers (Cu, Au) has been accomplished, highlighting the usefulness of the silver complexes as an easy to handle, air- and moisture-stable source of these ligands. Preliminary results indicate that dinuclear copper(I) complexes with N-phosphorylated imidazolylidene ligands display notable catalytic efficiency in nitrene transfer reactions.
