The Diels–Alder reaction of 5,8-quinolinedione with p-(dimethylamino)styrenes gave new two kinds of isomeric dyes, 2-(dimethylamino)naphtho[1,2-g]quinoline-7,12-diones and 2-(dimethylamino)naphtho[2,1-g]quinoline-7,12-diones, which showed quite different metallochromic behaviors. Upon addition of metal salts, one of the two isomers showed drastic spectral changes to have an intense absorption band
5,8-喹啉二酮与对-(二甲氨基)苯乙烯的Diels-Alder反应得到了两种新的异构染料,2-(二甲氨基)萘并[1,2-g]喹啉-7,12-二酮和2-(二甲氨基)萘并[2,1-g]喹啉-7,12-二酮,显示出完全不同的金属变色行为。添加金属盐后,两种异构体之一显示出剧烈的光谱变化,在近红外区域具有强烈的吸收带。研究了颜色-结构关系。
