Abstract
Periodic mesoporous organosilicas (PMO) which incorporate an optically active molecule into the material for use as an optical indicator of target binding. This material combines the stability, selectivity, and high density of binding sites characteristic of the PMO with the sensitivity and selectivity of the optically active molecule. The material undergoes a change when exposed to a sample containing a target molecule. The change can be observed by visual inspection or through the use of fluorescence spectra.
