Fluorescent whitening agents are applied to textiles and papers to enhance their whiteness and brightness through absorbing ultraviolet light region and emit blue fluorescence. In this study, a series of stilbene-triazine derivatives were synthesized through 3steps nucleophilic substitution reaction using two types of aniline and two amine substituents. The stilbene-triazine derivatives were characterized by MALDI-TOF MS analysis, UV-vis absorption, fluorescence emission spectroscopy. We evaluated their dyeing affinity and whiteness properties to the paper. The UV absorptions of the derivatives were in the ultra violet region (300–370nm) and their strong fluorescence emission peaks of the derivatives were in the blue region (400–460 nm). The whiteness data indicated that all the derivatives showed excellent whitening effect compared to undyed paper. In addition, when Aniline-2,5-disulfonic acid and Morpholine were introduced, the whiteness and dyeing affinity was most improved. |
