Abstract:
Chiroptical polythiophene (PTh), as one of the most important chiral conductive polymers, is an emerging and hot topic in chiral materials, which shows great application potentials in fields as diverse as chiral sensing and separation, asymmetry catalysis, chiroptoelectronics, and even chiro-spintronics. This review summarizes progress in chiral polythiophenes (PThs) in the past 10 years, including the synthesis, properties and applications. Main focus is placed on the manner in which chirality is implemented and the optical activity of the chiral PThs. We showcase examples in which the chirality of PThs is induced by side chain substituents with point, planar, and axial chirality or arises from external chiral media. Application of chiral PThs is also included. Finally, perspectives for further development are offered.
摘要:
手性聚噻吩(PTh),作为最重要的手性导电聚合物之一,是手性材料中一个新兴的热门话题,在手性传感和分离等领域显示出巨大的应用潜力,不对称催化,chiroptoelectronics,甚至chiro-自旋电子学。本文综述了近10年来手性聚噻吩(PThs)的研究进展,包括合成,属性和应用。主要关注实现手性的方式和手性PThs的光学活性。我们展示了一些例子,其中PThs的手性是由带有点的侧链取代基诱导的,平面,和轴向手性或来自外部手性介质。还包括手性PThs的应用。最后,提供了进一步发展的前景。
