An efficient strategy to investigate the window pore size of the silica shell generated by the Stöber method is achieved by the unique aggregation‐induced emission (AIE) property of Au(I)‐thiolate complexes, as presented by J. Xie and co‐workers on page 6537. The window size of silica shell is determined by screening the hydrated diameters of the probing metal ions, which can permeate through the silica shell and induce the aggregation of the Au(I)‐thiolate complexes, generating strong luminescence via the AIE mechanism.
