The present study describes new polynuclear Au(I) complexes and their unique luminescent properties. The emissive properties of these Au(I) complexes have been found to be sensitive to environmental factors such as volatile organic vapors, temperature, pressure, and etc. as well as the extent of Au(I) aggregation. Thiouracilate Au(I) complexes exhibit a solid-state luminescence tribochromism in which photoemission turns on and off upon gentle grinding of the sample. Furthermore thermochromism and solvochromism were observed for dithiophosphate Au(I) complexes. The variation of λemmax suggests the ways of systematically tuning the excited states through chemical environment factors and the brightness of the solid-state emissions for these new Au(I) complexes make these systems of interest for possible application as dopant emitters in OLED displays.
