Abstract

Reaction of the PNNP ligand system ,'-bis[(2-diphenylphosphino)phenyl]formamidinate (dpfam) featuring different coordination compartments with [AuCl(tht)], [CuMes], [AgMes], or [AuCF(tht)] (tht = tetrahydrothiophene) resulted in tetranuclear homo- and heterometallic coinage metal complexes, as well as a hexanuclear gold complex. All of them feature a metal string conformation. Photophysical investigation revealed a significant dependence of the photoluminescence properties on the metal composition. Below 100 K, the PL efficiency of three compounds approaches nearly 100%.

摘要

PNNP配体体系，即'-双[(2-二苯基膦基)苯基]甲脒（dpfam），其具有不同配位区域，与[AuCl(tht)]、[CuMes]、[AgMes]或[AuCF(tht)]（tht = 四氢噻吩）反应，生成了四核同金属和异金属的铸币金属配合物，以及一种六核金配合物。它们均具有金属链构象。光物理研究表明，光致发光性质对金属组成有显著依赖性。在100 K以下，三种化合物的PL效率接近100%。
