手性是自然界中普遍存在的有趣现象之一,在生命体中手性大分子特有的不对称结构在维持生命过程、新陈代谢和进化等面均起着决定性作用.受此启发,合成具有新型结构的光学活性聚合物,研究其独特的物理化学性质和功能已成为当今高分子领域研究的热点.左旋和右旋的圆偏振光已被广泛应用于氨基酸衍生物的不对称光合成、光分解和去消旋化反应,以及诱导含有偶氮苯或三苯胺等特定功能基团的超分子组装体或无机纳米粒子形成稳定螺旋结构.本文详细地介绍了圆偏振光辐照在手性聚合物合成与螺旋结构调控中的应用,初步揭示了圆偏振光的作用机制以及优势,归纳总结了已取得的研究进展,并对圆偏振光在手性聚合物合成与结构调控中的应用及发展进行了简单的评述和展望.
Chirality is one of the most common and interesting phenomena in nature. The unique asymmetric structure of chiral macromolecules in living organisms plays a decisive role in maintaining life processes, metabolism and evolution, etc. Inspired by this, synthesis of novel structures with novel structures Of the optically active polymers, to study its unique physicochemical properties and functions has become a hot area in the field of polymer research.L-spin and dextrorotatory circularly polarized light has been widely used in the asymmetric synthesis of amino acid derivatives, photodegradation and to Racemization reaction and the induction of supramolecular assemblies or inorganic nanoparticles containing specific functional groups such as azobenzene or triphenylamine to form a stable helical structure.In this paper, the effects of circularly polarized light irradiation on the synthesis of chiral polymers and The application and development of helical structure control are discussed. The mechanism and advantages of circularly polarized light are preliminary revealed. The progress of the research has been summarized. The application and development of circularly polarized light in the synthesis and structure control of chiral polymers have been simplified Comment and Outlook.
