Abstract

Abstract : 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.
