通过在2和4位引入两个甲基，7-羟基喹啉类化合物在水溶液中的光敏性得到了显著的提高。7-羟基-2，4-二甲基喹啉的摩尔消光系数与荧光量子产率(e·Φf)的乘积约为原来的13倍。
Significant enhancement of the photosensitivity of 7-hydroxyquinolines in aqueous buffer solution has been achieved simply by introducing two methyl groups at 2 and 4 positions. The product of the molar extinction coefficient and fluorescence quantum yield (e · Φ f ) for 7-hydroxy-2,4-dimethylquinoline is about 13-fold greater than that of original 7-hydroxyquinoline.
