水溶性共轭聚电解质

水溶性共轭聚电解质主要是指含离子型官能团侧链的共轭聚合物,可在水或其它极性有机溶剂中能够溶解。这类化合物把传统共轭聚合物的光电性质和聚电解质的水溶性特点结合在一起,显示出的一些独特性质,可在新一代光电器件制作和化学生物荧光传感器中获得多样的应用。本文总结了近10年来报道的水溶性共轭聚电解质的结构特点和合成方法,以及对不同化学或物理条件下光物理性质的研究,归纳了它们在新一代光电器件制作和荧光传感中的应用,并在此基础上提出了水溶性共轭聚电解质研究中尚待解决的问题,并展望了水溶性共轭聚电解质的应用前景。

Water-Soluble Conjugated Polyelectrolytes

Water-soluble conjugated polyelectrolytes (WSCPs) are novel types of conjugated polymers which contain ionic side chains, hence they are soluble in water and some other polar organic solvents. These polymers combine the optoelectronic advantages of traditional conjugated polymers with water solubility and ionic nature of polyelectrolytes. This research field is becoming more and more attractive due to their unique optoelectronic properties that may serve as the basis for a new generation of optoelectronic devices and bio/chemical sensors. In this paper, we summarize the synthetic methods, structure features and photophysical properties of WSCPs developed in recent ten years, and their applications in a new generation of optoelectronic devices and bio-chemical detection. On this basis, we point out the existent problems in the present research and applications of WSCPs,and also give a perspective on their future.
