Liquid crystal (LC) is thought to be an organized solvent(media). However, the researches on how supramolecular polymer behaves in LC media are rarely reported. Recently, our group reported a system in which chiral disc-shaped molecule supramolecularly polymerize in and co-assemble with an achiral LC-forming rod-shaped molecule resulting as a hybrid columnar LC. During this supramolecular polymerization, chirality is transferred to liquid crystalline media from supramolecular polymer. Based on this previous work, the present research introduced a chiral LC-forming media 5*CB, to act as chiral auxiliary/promoter in which disc-shaped molecule could supramolecularly polymerize into one-handed helical structure. This research for the first time discussed: (1) Symmetry Breaking induced by Chiral Liquid Crystalline Media: The construction of a one-handed hybrid columnar LC with porphyrin-core discshaped molecule and chiral LC-forming rod-shaped molecule. (2) Chirality amplification phenomenon of Supramolecular Polymer in liquid crystalline media.

液晶（LC）被认为是一种有机溶剂（介质）。然而，关于超分子聚合物在液晶介质中的行为的研究却鲜有报道。 最近，我们的研究小组报道了一个系统，其中手性盘状分子超分子包覆和共组装与非手性LC形成的棒状分子产生的混合柱状LC。在这种超分子聚合过程中，手性从超分子聚合物转移到液晶介质中。 在此基础上，本研究引入了一种手性液晶形成介质5*CB，作为手性辅助/促进剂，使盘状分子在超分子状态下形成单手螺旋结构。本研究首次讨论了：（1）手性液晶介质诱导的对称性破缺：以卟啉为核的盘状分子和手性液晶形成的棒状分子构成单手混合柱状液晶。(2)超分子聚合物在液晶介质中的手征放大现象。
