摘要
以4-溴-1,8-萘酐为原料,经亚胺化、乌尔曼缩合、Pschorr闭环等反应,合成了N-羟乙基-苯并硫杂蒽3,4-二甲酰亚胺(1)和7H-苯并咪唑[2,1-a]苯并硫杂蒽-7-酮及异构体(Ⅱ和Ⅱ'),测定了它们的吸收光谱和荧光发射光谱以及光化学稳定性。塑料ABS经它们着色后,荧光效果非常明显。
N-hydroxyethyl-Benzo[K. 1] thioxanthene-3, 4-dicarboximide(Ⅰ) and 7H-benzimidazo[2,1-a ]benz [d, e] isoquinolin-7-one(Ⅱ) together with its isomer(Ⅱ’) were synthesized through imidation, Ullmann condensation and Pschorr ring close reaction with 4-bromo-1, 8-naphthailc anhydride as starting material. Their absorption spectra and fluorescence emission spectra were measured and photo-stability was tested. They can colour plastics as fluorescent dyes.
