摘要

以乙烯基和咪唑基为主要基团的a2b2型卟啉锌（ZnPorI2）为材料，制备了多孔有机聚合物（POPs）。乙烯基作为与刚性二乙烯基苯（DVB）共聚的连接单元。咪唑基团将碘离子（I−）引入ZnPorI2/nDVB （n= 30,50）中作为路易斯碱。通过调整ZnPorI2与DVB的比例，可以优化zn -卟啉的孔隙度、形貌和含量。由于Zn2+和I−的协同作用，制备的ZnPorI2/30DVB在二氧化碳与环氧化物的环加成反应中表现出优异的催化活性。

A2B2-zinc(II)porphyrin/divinylbenzene Copolymer as Efficiently Bifunctional Catalyst for Cycloaddition of CO2 with Epoxides

In this work, the A₂B₂-type Zn-porphyrin (ZnPorI₂) featuring vinyl and imidazolium groups was utilized to prepare porous organic polymers (POPs). The vinyl group served as the linking unit for copolymerization with rigid divinylbenzene (DVB). The imidazolium group introduced iodide ions (I⁻) into ZnPorI₂/nDVB (n=30, 50) as Lewis base. By fine-tuning the ZnPorI₂ to DVB ratio, it is possible to optimize the porosity, morphology, and content of Zn-porphyrin. Owing to the synergistic effect of Zn²⁺ and I⁻, the as-prepared ZnPorI₂/30DVB exhibited excellent catalytic activities in the cycloaddition of carbon dioxide with epoxides.
