A selective and sensitive fluorescent chemosensor for Hg2+, which was composed of two aminonaphthalimide fluorophores and a receptor of 2,6-bis(aminomethyl)pyridine, was synthesized through the reaction of 2,6-bis(chloromethyl)pyridine and N-[2-(2-hydroxyethoxy)ethyl]-4-piperazino-1,8-naphthalimide. The chemosensor showed an about 17-fold increase in fluorescence quantum yield upon addition of 1 equiv of Hg2+ in neutral buffer aqueous solution, and the other common metal ions did not notably disturb the detection of Hg2+.
一种用于Hg2+的选择性灵敏荧光化学传感器,由两个氨基萘二甲酰亚胺荧光团和一个2,6-双(氨甲基)吡啶受体组成,通过2,6-双(氯甲基)吡啶与N-[2-(2-羟基乙氧基)乙基]-4-哌嗪基-1,8-萘二甲酰亚胺反应合成。在中性缓冲水溶液中加入1当量的Hg2+后,该化学传感器的荧光量子产率提高了约17倍,其他常见金属离子不会显著干扰Hg2+的检测。
