| Abstract：An optical brightener 4-(5-methylbenzoxazol-2-yl )-4'-( benzoxazol-2-yl ) stilbene was synthesized by additive cyclization, esterification and condensation using 4-cyanobenzyl chloride, o-amino-4-methylphenol and 4-formylphenylbenzoxazole as starting materials. The yield of the three steps was over 85%, 92% and 91%, respectively. The obtained product was characterized by element analysis, IR and UV and its purity was over 99%. |
