二氧化碳（CO2）浓度过高引起的气候变化已成为当前人类生存与社会发展所面临亟待解决的问题。以CO2为原料合成高附加值化学品环状碳酸酯，可减少其他化工原料消耗，并为降低CO2的浓度、缓解温室效应提供有效途径。本项目拟将富氮配体六氮杂苯并菲（HAT）通过简单的氨基和羰基的缩合反应引入到三蝶烯微孔聚合物框架中，通过配位金属离子，构建能同步实现CO2捕获与转化双功能的氮杂三蝶烯微孔聚合物（HAT-TP）体系。HAT单元的引入，不仅增加了聚合物中具有亲CO2的氮原子含量，提升CO2捕获能力；还增加了金属离子配位点，提升金属离子的配位强度，既保证了初始的催化活性也能避免循环使用中金属离子流失带来的活性降低。项目通过对HAT-TP的合成，不同金属离子的配位，CO2转化的催化活性考察，及催化机理的推测，构建能同步实现CO2捕获与转化双功能非均相多孔催化体系，为有机孔材料的应用和降低CO2浓度提供新思路。

The greenhouse effect caused by increasing CO2 concentration in the atmosphere has led climate change and environmental issues. The development of efficient and cost-effective methods for CO2 capture and reversion to organic compounds is an important goal for human society over the course of this century. In this project, we are going to introduce hexaazatriphenylene – the nitrogen-riched units into the triptycene-based microporous polymer scaffolds by the condensation reactions of amino and carbonyl groups. In these polymers, abundant nitrogen atoms and their rational spatial distribution, is conducive to enhance the ability to carbon dioxide capture and chelating metal ions, which ensure the initial catalytic activity and avoid the reduction of the activity of metal ions in the circulation. This project covers synthesis of aza-fused triptycene-based microporous polymers, loading the metal ions on this polymer, evaluation of their catalytic activity, optimization of the catalytic conditions and exploration the catalytic mechanism, which may lay a foundation for the development of a dual functional heterogeneous catalytic system for carbon dioxide capture and conversion.
