In article number 1906665, Kazuo Akagi and co‐workers report the synthesis of a novel chiral compound comprising two types of chiral moieties with opposite helicities and temperature dependences, which they then add as a chiral dopant to a mixture of nematic LCs to prepare a chiral nematic liquid crystal (N*‐LC). The N*‐LC exhibits thermally invertible helicity to yield left‐ and right‐handed helical senses at low and high temperatures, respectively, which enables the production of helicity‐controlled helical conjugated polymers.

手性液晶：具有热可逆螺旋感的手性反应场，可控制共轭聚合物的螺旋度（Adv。Mater。12/2020）

在第1906665号文章中，Akagi Kazuo及其同事报告了一种新型手性化合物的合成，该化合物包含两种类型的具有相反螺旋度和温度依赖性的手性部分，然后将它们作为手性掺杂剂添加到向列LC混合物中以制备手性化合物。向列液晶（N * ‐LC）。N * -LC表现出热可逆的螺旋度，分别在低温和高温下产生左旋和右旋螺旋感，这使得能够生产由螺旋度控制的螺旋共轭聚合物。
