【摘要】 聚乙炔是链对称的共轭大分子,在内外界的微扰下,其主链的对称性能够被破坏,而产生螺旋手性结构。本文综述了螺旋手性聚乙炔衍生物的合成和功能方面的研究进展,着重介绍了螺旋手性聚乙炔衍生物在简单的外界刺激(溶剂、酸碱度、温度和添加剂等)下,表现出许多功能特征,如刺激响应性、显色、光/电致发光,仿生结构,分子识别等。更多还原

【Abstract】 Polyacetylene(PA) is a symmetric chain conjugated macromolecule,whose chain symmetry can,however,be broken by external and internal perturbations,generating helically chiral polymers.In this article,progress on syntheses and functions of helically chiral polyacetylene derivatives is reviewed.It is emphasized that helically chiral PA derivatives show various functional properties such as stimuli-response,chromism,photo-and electroluminescence,biomimetic structures,molecular recognition etc,through simple external stimulate such as solvent,pH,temperature,additives etc.更多还原
