金属有机框架材料（MOFs）由于其在气体吸附分离、催化反应、药物控释等方面的优秀性质，引起了人们广泛的关注。设计与合成新结构、新性能的金属有机框架材料已成为化学和材料学科研究中最为活跃的领域之一。如何定向设计和构筑基于柔性配体的MOF材料是目前该领域尚未解决的一大难题。本申请项目拟将配位聚合物和超分子机械互锁结构相结合，发展一种新的合成策略，以实现定向地构筑基于柔性配体的金属有机框架。在研究系列新颖的轮烷型配体与Cu、Zn、及Zr金属离子的配位规律的基础上，通过MOF后合成方法，进一步获得了传统方法不能制备的新结构与新材料，为金属有机框架材料的控制合成和功能优化提供新的思路和启发。

Metal-Organic Frameworks (MOFs) has attracted great attention due to its exceptional performance in applications such as gas absorption and separation, catalysis, and drug delivery. The design and synthesis of new structure and novel functionalized MOFs has become one of the hot research filed of chemistry and material science. However, constructing MOFs from flexible ligands remains a big challenge due to the soft nature of the ligand. In this proposal, we developed a new strategy for fabrication of MOFs based on soft and flexible ligand through the combination of coordination chemistry and supramolecular chemistry. A comprehensive study of the coordination chemistry of a series of rotaxane ligands to metal ions (Cu, Zn and Zr) was conducted. With the assistance of MOF Post-synthesis, we eventually obtained a series of materials which are not accessible when we use conventional methods. This new strategy would not only provide new insights for controlled synthesis of MOFs, but also inspirations for optimization of their functions.
