Probing the Microporous Structure of Silica Shell Via Aggregation‐Induced Emission in Au(I)‐Thiolate@SiO2 Nanoparticle

An efficient method to investigate the window size of the silica shell generated via the classical Stöber method is reported by making use of the unique aggregation-induced emission property of Au(I)-thiolate complexes, which can precisely probe the porosity of the silica shell in Au(I)-thiolate@SiO2 nanoparticles.
