Abstract

The effects of diphosphine flexibility and bite angle on the structures and luminescence properties of Au(I) complexes have been investigated. A range of diphosphines based on heteroaromatic backbones [bis(2-diphenylphosphino)phenylether (dpephos), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (xantphos), and 4,6-bis(diphenylphosphino)dibenzofuran (dbfphos)] has been used to prepare mono- and digold derivatives. A clear relationship between the presence of aurophilic contacts and the emission properties of dinuclear complexes has been observed, with one of the complexes studied, [Au(2)Cl(2)(micro-xantphos)], exhibiting luminescence thermochromism.

摘要

研究了二膦的柔韧性和咬合角对金（I）配合物结构和发光性质的影响。使用了一系列基于杂芳族骨架的二膦[双（2-二苯基膦基）苯基醚（dpephos）、9,9-二甲基-4,5-双（二苯基膦基）呫吨（xantphos）和4,6-双（二苯基膦基）二苯并呋喃（dbfphos）]来制备单核和双核金衍生物。已观察到亲金相互作用的存在与双核配合物的发射性质之间存在明确的关系，所研究的配合物之一[Au(2)Cl(2)(μ-xantphos)]表现出发光热致变色。
