摘要：
A series of fluorescent brightening agents containing pyrazolyl or triazolyl groups were synthesized in this work and their structures were confirmed by IR, H-1 NMR and C-13 NNIR determination. UV absorption spectrometry was employed to investigate the process of photoisomerizations of some stilbene-derived fluorescent brightening agents. Their fluorescence spectra were also studied and discussed. (C) 2004 Elsevier Ltd. All rights reserved.
