萘酰亚胺类共聚色素的合成

Sduty on Copolymeric Colorant of Naphthlic Imide Derivatives

以６－溴－１Ｈ，３Ｈ－萘并［１，８－ｃｄ］吡喃－１，３－二酮为原料，经亚胺化、Ｕｌｍａｍｎ缩合后与丙烯酰氯酯化得到具有荧光的可聚合单体６－（Ｎ－丙烯酰氧乙基）氨基－２－（２’，４’－Ｎ，Ｎ－二甲基）苯基－１Ｈ－苯并［ｄｅ］异喹啉－１，３（２Ｈ）－二酮，它与甲基丙烯酸甲酯经自由基共聚得到具有强烈荧光的聚合色素。

With 6-bromo-1H,3H-naphthopyran-1,3-dione as starting material, 6-(N-acryloxy-ethyl)amino-2-(2',4'-dimethyl)amino-1H-benzisoquinolin-1,3(2H)-dione was synthesized through imidation, Ulmamn condensation and esterification. The title copolymer, which showed intensive yellowish-green fluorescence, was then obtained through free radical copolymerisation. Its molecular weigh distribution, absorbing spectra and fluorescence spectra were measured.
