基于轮烷构筑的三维共价有机框架及其性能研究

共价有机框架材料（COFs）由于其在气体吸附分离、催化反应、光电等方面的优秀性质，引起了人们广泛的关注。设计与合成新结构、新性能的共价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。目前对于二维COF材料研究报道较多，但对于含有三维空间拓扑结构共价有机框架材料的研究报道相对甚少，三维COF材料的结构设计和功能应用是目前材料化学领域极具挑战的难题之一。本申请项目拟将超分子机械互锁结构应用于共价有机框架的合成，以获得结构新颖的新材料。最后，通过后合成方法，进一步获得了传统方法不能制备的新结构与新材料，为共价有机框架材料的结构设计和功能优化提供新的思路和启发。

Covalent Organic Frameworks (COFs) has attracted great attention due to its exceptional performance in applications such as gas absorption and separation, catalysis, and optoelectronics. The design and synthesis of COFs with new structure and novel functions has become one of the hottest research filed of chemistry and material science. Although the 2D COFs has been well studied in the past years, the structural design and applications of 3D COFs remains one of the biggest challenge in material science. In this proposal, we aim to obtain new metarials by applying the mechanically interlocked structures in the synthesis of Covalent Organic Frameworks. Eventually, new structures and materials can be obtained through the post-synthesis. This new strategy would not only provide new insights for structural design of COFs, but also inspirations for optimization of their functions.
