Probing the molecular character of periodic mesoporous organosilicates via photoluminescence of Lewis acid–base adducts

Abstract

Photoluminescence decay was used as a structure-sensitive method to compare the distribution of emitting sites in periodic mesoporous organosilicates (PMOs) to their respective molecular analogs. The observed close similarity of PL decays confirms the molecular nature of PMOs and high homogeneity of emitting sites.
