摘要
通过整理金属卟啉聚合物催化环氧烷烃与CO2的制备环状碳酸酯相关文献,发现具有高比表面积的金属卟啉基多孔聚合物、卟啉环中心金属及小分子聚合单体中的亲核离子是温和条件下高效催化该反应的主要原因,目前合成的金属卟啉聚合物存在孔道易变小、结构不稳定、难以适应大尺寸的环氧化物等问题,如何设计制备空间位阻小、性能稳定、拥有大量Lewis酸碱高活性中心的双活性位点金属卟啉基多孔聚合物是未来此类催化剂的主要发展方向.
Abstract
This article reviews the preparation of cyclic carbonates from alkylene oxides and CO2 catalyzed by metalloporphyrin polymers.It is found that metalloporphyrin-based porous polymers have high specific surface area,central metal of the porphyrin ring and nucleophilicity in small molecule polymerized mono-mers,which are the key points for efficiently catalyzing the cycloaddition reaction of epoxides and CO2 un-der mild conditions.However,currently synthesized metalloporphyrin polymers have some problems,such as easy pore size,unstable structure,and difficulty in adapting to large-sized epoxides.In the future,we should focus on designing and preparing dual-active site metalloporphyrin-based porous polymers with small steric hindrance,stable performance,and a large number of Lewis acid-base highly active centers,which is the direction we need to research in the future.
