晶态超分子材料具有独特的结构与功能，在诸多领域具有重要的应用前景，是晶态材料研究的热点之一。目前这一领域大部分研究关注于特定结构的构筑，对功能导向的研究相对较少，该领域还存在着很多亟待解决的重要科学问题，如：功能导向晶态材料的定向设计及可控制备问题；功能基元的组装及空间拓展方式问题；功能基元空间排布与材料宏观性能表现之间的关联问题等等。本项目拟围绕这些重大科学问题，提出扩展的功能基元概念，以功能导向的晶态超分子材料的构筑及性质研究为目标，从功能基元的设计出发，改变其在空间中的排布及取向，进而实现材料结构及性能的调控，在此基础上探索和阐明材料性能与功能基元的结构及空间排布之间的关联，分析材料产生特殊性能的机理，总结规律，进一步通过对功能基元结构的调整以及空间排布方式的优化实现材料性能的提升，为功能导向的晶态材料的构筑提供新的理论依据及实验手段。

Crystalline supramolecular materials, owing to their unique structures and properties, have shown potential applications in many fields and become a hot topic in crystalline material research. Until now, much attention in supramolecular fields has been attracted to the construction of special self-assembled architecture, while the function-targeted construction of materials is still a great challenge. Aiming at this challenge, a new concept of “functional motifs” has been raised in this project, based on which the functional-targeted construction of crystalline supramolecular materials could be achieved by modifying the arrangement and orientation of the “functional motifs”. Furthermore, the relation between the structure and the properties of the materials could be achieved, which could be instructive for the structure and properties optimization of the materials. The achievements of the project will contribute to the function-targeted construction of crystalline supramolecular materials in both theoretical and experimental manners.
