Chemical conversion of carbon dioxide (CO₂) to value-added useful chemicals like cyclic carbonates represents one potential solution to climate warming. Here, a kind of porous organic polymer (HAT-TP) with large surface area and excellent carbon dioxide uptake capacity is prepared via a condensation reaction to introduce hexaazatriphenylene (HAT) units into triptycene (TP)-based microporous polymer. HAT-TP can coordinate with zinc ions, and the resulting polymer (Zn/HAT-TP) can be utilized as an efficient recyclable catalyst for chemical conversion of CO₂ into cyclic carbonates with epoxides.

基于六氮杂三苯并三苯并茂的微孔聚合物用于CO 2捕获和转化

将二氧化碳（CO ₂）化学转化为增值的有用化学物质（例如环状碳酸酯）是解决气候变暖的一种潜在解决方案。在此，通过缩合反应将六氮杂三苯撑（HAT）单元引入基于三萜烯（TP）的微孔聚合物中，制备了一种具有大表面积和优异的二氧化碳吸收能力的多孔有机聚合物（HAT-TP）。HAT-TP可以与锌离子配位，所得的聚合物（Zn / HAT-TP）可以用作有效的可回收催化剂，用于将CO ₂与环氧化物化学转化为环状碳酸酯。
