Upon
photoirradiation, isomerization of the ligands, 1,2-bis(diphenylphosphino)ethene
(dppee) from the cis to the trans form in polynuclear gold(I) sulfido
clusters, led to the structural transformation of the decagold(I)
cluster to the octadecagold(I) cluster. Both polynuclear μ3-sulfido gold(I) clusters have been fully characterized by
NMR, mass spectrometry, elemental analysis, and single crystal X-ray
diffraction analysis. The transformation process could be readily
detected and monitored by UV–vis absorption, emission, and 31P NMR spectroscopy in solution. Supported and driven by Au(I)···Au(I)
bonding interactions, the nuclearity and symmetry of these clusters
were largely different from each other, resulting in completely distinct
photophysical features.
