Abstract

A tridentate trimethylstannyl substituted alkyne based on the tribenzotriquinacene (TBTQ) scaffold has been transformed into several gold(I)phosphane complexes by tin-gold exchange. While the molecular structures of the gold(I) derivatives with less bulky trimethyl and dimethylphenylphosphane ligands exhibit intermolecular aurophilic interactions, the sterically demanding triphenylphosphane ligands inhibit the occurrence of Au⋅⋅⋅Au contacts. In addition, a hexanuclear gold(I) system was synthesised by terminal functionalisation of the hexaalkynyl TBTQ. Investigations of the photophysical properties of the gold(I)phosphane TBTQ compounds revealed their luminescent character at room temperature.

基于三苯并三醌的三核和六核金(I)体系

以三苯并三醌（TBTQ）为骨架的三甲基锡基取代炔通过锡金交换转化为几种金(I)磷化配合物。具有体积较小的三甲基和二甲基苯基膦配体的金(I)衍生物的分子结构表现出分子间亲金相互作用，而具有空间要求的三苯基膦配体则抑制Au⋅⋅⋅Au接触的发生。此外，通过六炔基TBTQ的末端功能化，合成了六核金(I)体系。对金(I)磷化TBTQ化合物的光物理性质进行了研究，揭示了它们在室温下的发光特性。
