Brief Communications


The spectroscopic kinetic characteristics of the fluorescence of anthracene adsorbed on silica gel have been investigated. The formation of charge-transfer (CT) complexes between the anthracene molecules and acceptor sites on silica gel which had been heat-treated in a vacuum has been discovered. Along with the emission of the CT complexes, the luminescence of an excited CT complex, i.e., an exciplex, has been detected. Hypotheses regarding the nature of the electron-acceptor sites on silica gel have been advanced.
