Phosphorescence of aromatic compounds is studied in porous sol-gel matrices at liquid nitrogen temperature. Spectral and kinetic parameters of phosphorescence are found to depend on a matrix and the nature of the activator molecules. In the case of carbonyl compounds, this dependence is determined, in our opinion, by the interaction between the carbonyl group of a molecule and the hydroxyl groups of a matrix, which are bonded to surface silicon atoms. 18 refs., 7 figs.
