中文摘要： 超分子手性材料将分子尺度手性进行放大，凭借其独特的尺度范围和不对称特性而具有诸多奇特的光学性质，在不对称催化、手性识别、手性分离等方面有着重要应用。但超分子手性材料常以溶液态形式存在，极大地限制了其在光学材料领域的应用开发。本项目针对这一问题，将反相微乳液受限空间调控自组装与乳液聚合两项技术有机结合，构筑集成四磺酸基苯基卟啉（TPPS）超分子手性聚集体的聚甲基丙烯酸甲酯（PMMA）固体复合材料。随后尝试将该材料加工为几种光学器件，预计在非线性光学及激光滤波等领域探索此类材料的应用，建立手性信号和材料宏观性质的关系及其规律，为新型光学器件的开发与设计提供科学依据。. 集成超分子手性光学性质的固体复合材料为光学器件开发提供了新思路，也对于超分子手性材料的应用开发具有重要意义。

英文摘要： Supramolecular chiral materials can amplify the molecular chirality into special length scales. Due to the mesoscopic asymmetry, supramolecular chiral materials have fantastic optical properties and significant applications in the fields of asymmetric catalysis, chiral recognition and chiral separation. However, supramolecular chiral materials always exist as solution, which intensively restricts the application development of supramolecular chiral materials in the field of optical materials. In order to address this problem, 5,10,15,20-tetrakis-(4-sulfonatophenyl)-porphyrin (TPPS)/ polymethyl methacrylate （PMMA） composite with integration of chiral aggregates of TPPS will be fabricated with the combination of self-aggregate modulated by confined space (inverse microemulsion) and polymerizable microemulsion. After being processed into several kinds of optical devices, the application of this material will be explored in the fields of nonlinear optics and laser filtering. This study can make connections between the chiral signal and the macroscopic properties and provide scientific basis for the development and design of optical devices.. Solid composite with integration of fantastic optical property of supramolecular chiral aggregates provides new insight into the development and design of optical devices. It is also meaningful for the application development of material with internal supramolecular chirality.
