Abstract

A simple fluorescent chemosensor 2-(furan-2-yl)-4,5-diphenyl-1H-imidazole (P1) based on an imidazole furan conjugate has been designed, synthesized and characterized. Fluorimetric studies on chemosensor P1 showed excellent selectivity toward Cu²⁺ ions over other metal ions in aqueous media through a “turn on−off” process. A possible reverse photoinduced electron transfer mechanism is proposed. The viability of P1 to Cu²⁺ has been demonstrated by live cell imaging.

咪唑衍生物在水和生物介质中荧光检测和测定铜（II）中的应用

摘要

设计，合成和表征了一种基于咪唑呋喃共轭物的简单的荧光化学传感器2-（呋喃-2-基）-4,5-二苯基-1H-咪唑（P1）。对化学传感器P1的荧光研究表明，通过“打开-关闭”过程，在水性介质中对Cu ²⁺离子的选择性优于其他金属离子。提出了一种可能的反向光致电子转移机理。已通过活细胞成像证明了P1对Cu ²⁺的活力。
