Abstract

Abstract: The fluorescence spectra of 3,4,9,10-tetramethylperylene(TMP)has been studied by means of steady-state and transient fluorescence measurements and compared withthat of perylene(PE).The fluorescence of TMP and PE can be quenched by nitromethane,nitrobenzene and 4-nitrobenzaldehyde,and the quanching efficiency wais increased withthe increase of the electro-withdrawing ability of the quanchers.The derivation of F₀/F from Stern-volmer equation was explained in terms of active sphere and the quanchingmechanism has been discussed, From the excitation spectrum,the charge transfer complexbrmed between TMP and tetrabutylammonium hexafluoroarsonate in electrochemical cellhas been detected.

Key words: tetramethylperylene, fluorescence spectrum, mechanism of fluorescence quanching, charge transfer complex
