Stimuli-Responsive Luminescent Material Based on Supramoleculary Hybridized Hierarchical Assembly

液晶(LC)被认为是一种有组织的溶剂(介质)。然而，关于超分子聚合物在液晶介质中行为的研究却鲜有报道。最近，本课题组报道了一种手性盘状超分子与非手性棒状液晶分子聚合并共组装形成杂化柱状液晶的体系。在超分子聚合过程中，手性从超分子聚合物转移到液晶介质中。在前人工作的基础上，本研究引入了手性液晶形成介质5*CB，作为手性辅助/促进剂，盘状分子可以在其中进行超分子聚合，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：以卟啉为核心的盘状分子和手性形成的棒状分子构建了单手杂化柱状LC。(2)超分子聚合物在液晶介质中的手性放大现象

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.
