刚柔嵌段共轭聚合物的自组装是超分子化学研究的热点之一。本文综述了近年来刚柔嵌段共轭聚合物自组装体系的研究进展。根据共轭刚性段的不同分类进行阐述,综述了聚芴、二(苯乙烯)-蒽、聚对苯撑、聚对苯乙烯撑、聚对苯撑乙炔、聚(2,5-苯甲酮)、聚噻吩、聚苯基喹啉等作为刚性链段的刚柔嵌段共轭聚合物自组装体系,介绍了刚柔嵌段共轭聚合物的合成和光物理性质;重点评述了刚柔嵌段共轭聚合物在不同溶剂、浓度、温度等条件下自组装形成一维、二维以及三维的周期性微结构,且具有方便的可控性。概括了刚柔嵌段共轭聚合物自组装体系广阔的应用前景,尤其在光电器件领域有着潜在的应用价值。最后展望了刚柔嵌段共轭聚合物自组装体系研究和发展的方向。
The self-assembly of conjugated rod-coil block copolymers has recently become one of the hot topics in the research of supramolecular chemistry. This article reviews the program on the self-assembly of conjugated rod-coil block copolymers with different rod blocks, including polyfluorene, polydi （ styryl）-anthracene, poly （ para-phenylene）, poly （ para-phenyleneethynylene ）, poly （ para-phenylenevinylene）, poly （2, 5-benzophenone）, polythiophene, poly （phenylquinoline）, etc. The syntheses and photophysical properties of conjugated rod-coil block copolymers are introduced. The formation and regulation of well-defined one-, two-, or three-dimensional conjugated domains in nanoscale dimensions by the self-assembly of these copolymers in different solvents, temperature and concentration are reviewed emphatically. The potential applications of the self-assembly of conjugated rod-coil block copolymers in many fields, particularly in optoelectronic device, are summarized. Finally, the prospects for the self-assembly of conjugated rod-coil block copolymers are stated.
