Abstract: | The bimolecular photochemical quenching of the fluorescence of pyrene by N,N-dimethylaniline on the surface of various porous silicas with low coverage of the surface (less than a monolayer) has been studied. The kinetics of this process on porous and nonporous silica have been compared. Institute of Surface Chemistry, National Academy of Sciences of Ukraine, 31 Prosp. Nauki, 252039, Kiev.
