Abstract

Abstract Two new 7-N, N-diphenylamino-3-benzoheterocyclic coumarin derivatives containing electron-transporting benzotriazolyl or benzoxazolyl moiety, 3-(1-benzotriazole)- 7-N, N-diphenylaminocoumarin (BTDC) and 3-(2-benzoxazole)-7-N, N- diphenylaminocoumarin (BODC), were synthesized and characterized by element analysis, 1 H NMR and FT-IR spectra. The UV–vis and fluorescence spectra of these coumarin ...
