(a) Schematic illustration of solvent-induced AIE properties of oligomeric Au (I)-thiolate complexes. (b) Digital photos of Au (I)-thiolate complexes in mixed solvents of ethanol and water with different under visible (top row) and UV (bottom row) light. (c) UV-vis absorption and (d) photoemission spectra of Au (I)-thiolate complexes in mixed solvents with different . (Inset) Relationship between the luminescence intensity and . The spectra were recorded 30 min after the sample preparation. Reprinted with permission from [45], ©(2012), American Chemical Society.
