Abstract

It is important for the determination of biologically and/or environmentally relevant species by utilization of fluorescent probes. Conventional fluorescent probes are subjected to the influence of aggregation-caused quenching that is limiting their application due to low selectivity as well as photobleaching. Additionally, quencher pairs are usually introduced in the design of these probes, which lead to the complex synthetic procedure. A novel class of fluorogens with aggregation-induced emission (AIE) characteristic provide a solution to address the dilemma. By taking advantage of the unique characteristic of AIE fluorogens, specific turn-on probes have been developed via combination with recognition components, exhibiting low background, good selectivity and outstanding photostability. This review focuses on the development of fluorescent probes with AIE characteristics via the bond cleavage as well as formation strategy.

基于共价键变化的靶标响应性AIE荧光探针

摘要

荧光探针是检测生物或者环境中相关物质的重要手段. 传统 的荧光探针由于聚集诱导猝灭引起的选择性差异和容易光漂白等 问题限制了其应用. 此外, 在传统荧光探针的设计中通常引入猝灭 基团, 从而增加了探针合成及分离的难度. 一类新型的具有聚集诱 导发光(AIE)特征的荧光染料解决了上述问题. 利用AIE发光团的 独特性质, 构建发光团与识别基团偶联的特异性“关开型”探针, 这些探针具有背景低、选择性好和光稳定性强的优点. 本综述主要概括并讨论了通过共价键断裂以及新键形成策略开发的具有AIE特征的荧光探针, 并对其进行了展望.
