新型苯并氧杂蒽类荧光染料的研究

摘要

Nine novel fluorescent dyes of Benzoxanthene-3,4-dicarboxylic anhydride were synthesized through bromination,condensation,reduction,cyclization and imidation with 1,8-naphthalic anhydride as raw material.Their fluorescent and dyeing properties were studied.They can be used to color polyester fiber in fluorescent greenish-yellow hues of great brilliance with fastness to light:6～7．
