Template Sol-Gel Synthesis of Phosphorescent Mesoporous Silica Film Nanocomposites using an Amphiphilic Gold(I) Pyrazolate Complex

摘要

Herein novel mesoporous silica film nanocomposites are successfully synthesized by using phosphorescent columnar assembly of an amphiphilic trinuclear gold (I) pyrazolate complex [Au_3Pz_3] as a functional template in the sol-gel synthesis. By controlling the molar ratios of silica source tetrabutylorthosilicate (TBOS) to [Au_3Pz_3] in an acidic aqueous alcohol solution from 60:1 to 20:1, highly ordered phosphorescent nanocomposites can be fabricated with hexagonal [Au_3Pz_3]/silica_(hex) and lamellar [Au_3Pz_3]/silica_(lam) silicates.
