Tóm tắt

A charge-transfer-interaction mechanism has been proposed for the quenching of fluorescence of a number of polynuclear aromatic hydrocarbons by aromatic solvents, especially methylated benzenes. The quenching efficiency has been found to be in the order benzene<toluene<xylene<mesitylene, which is also the order in which ionization energy of the solvents diminishes.
