摘要

共轭高分子作为 "分子导线"所特有的信号放大效应

使其在构建高灵敏度的荧光化学传感体系中具有特别的优势。本文首先从分子识别、传感机理和信号输出等方面概述了传感分子设计中需要考虑的一些基本问题;然后以聚对芳撑乙炔类共轭高分子为例

提出基于模板排列组合的分子组装概念

并将之用于合成一系列结构可调的荧光化学传感分子

以满足不同的检测目的;最后通过文献中的具体实例

对多种聚对芳撑乙炔类共轭高分子进行了分子结构和传感应用方面的解析。

Abstract

Due to the unique amplified effect as molecular wires

conjugated polymers have advantage over small molecules in building up sensory systems with high sensitivity. This article presents several basic issues need to be considered in the design of fluorescent chemosensors

such as

the molecular recognition

the sensing mechanism and the read-out. Afterwards

the molecular assembly concept based on the combination of different functional modules was advanced for the synthesis of conjugated polymers with tuned properties to meet diverse sensing applications. Different poly(arylene ethylene)s (PAE) were used as examples to illustrate this concept. The sensing mechanisms as well as the applications of sensory systems were also discussed.
