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, [Au2Cl2(mu-xantphos)], exhibiting luminescence thermochromism.
