  Synthesis, Characterization, and Crystal Structures of 1,1-Disubstituted-2,3,4,5-tetraphenylgermoles That Exhibit Aggregation-Induced Emission

  摘要：

  A series of 2,3,4,5-tetraphenylgermoles with different 1,1-substituents have been prepared, and their UV-vis absorption and fluorescence spectral profiles in solution were determined. A thin-layer chromatography based method was used to measure their solid-state luminescence. Nine of the 11 new germoles have been characterized crystallographically. The aggregation-induced emission effect in these germoles was studied, and significant enhancement of the photoluminescence and quantum yield in mixed solvent-water systems was determined. Scanning and transmission electron microscopy analysis revealed the formation of nanocrystalline aggregates in the mixed solvent-water systems and after exposure of the germoles to acetone, a volatile organic chemical.
