摘　　要：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.作为二氧化碳化学转化的研究热点,利用二氧化碳作为原料合成有机小分子化合物被认为是解决温室效应的有效途径之一.本文合成了一种基于六氮杂苯并菲扩环三蝶烯的有机微孔聚合物(HAT-TP).该多孔聚合物表现出较高比表面积以及较好的二氧化碳吸附能力.通过与锌离子配位,Zn/HAT-TP聚合物还能够作为一类良好的非均相催化剂催化二氧化碳与环氧化物反应生成对应的环状碳酸酯.
