Synthesis and photoluminescent properties of 7 NN diphenylamino 3 benzoheterocy

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
