Abstract

Abstract: Fluorescence quenching and photoinduced electron transfer between several common materials,hole-transporting material,TPD,NPB and electron-transporting material,AlO₃ using in OLEDs were studied.Based on the measurement of fluorescence quenching constants of these compounds and the calculation of Gibbs’ free energy changing of these processes,it was concluded that the property of process studied in this work possesses character of electron transfer definitely.Compared their fluorescence quenching effect,ΔG,and T_g,NPB was thought to be a better hole transporting material than TPD.

Key words: fluorescence quenching, OLEDs, hole and electron transporting materials, photoinduced electron transfer
