新型编织微孔聚合物网络合成及其应用

Microporous organic polymers (MOPs) can be defined as porous materials with higher surface areas and pore sizes smaller on average than 2 nm which are comprised of light, non-metallic elements such as C, H, O, N, and B. In comparison with other microporus materials such as zeolites, silicon and metal-organic frameworks (MOFs), MOPs have the advantages that they combine high surface areas with good physical and chemical stability and synthetic diversity. However, the porosity in the MOPs is achieved mainly by the proper designing monomers with special structures. Moreover, toxic and expensive metal catalysits are usually used during the reaction process. All these factors are prone to increase the cost of the materials. In this project, we want to produce cost-effective microporous polymers with very high surface areas by using a simple one-step Friedel-Crafts reaction of aromatic compounds. The surface areas and pore size can be fine tuned by varying the mass of the external crosslinker. The functional networks and ordered molecular structure also can be obtained by choosing proper monomers and crosslinking at certain site, respectively. While, the applications of the knitting microporous organic polymers in heterogeneous catalysis and optoelectronics also will be studied. The results will benefit to the scienfic research and industry application of the microporous organic polymers.

微孔有机聚合物（microporous organic polymers，MOPs）是一类具有较大比表面积，包含大量尺寸小于2 nm孔道的聚合物多孔材料。它完全由较轻质量的元素C、H、O、N、B组成。与常规的微孔材料如沸石，硅胶和金属有机网络（MOFs）相比，MOPs兼有高比表面积，稳定的理化性能，以及合成多样性等优点。然而目前关于MOPs的合成通常需要精心设计单体结构，且合成过程涉及到较昂贵的催化剂，这必然会增加材料的生产成本。本项目拟采用低成本的原料和便捷的反应路径，一步法超交联各类具有芳环结构的单体，获得具有高比表面积的编织微孔聚合物网络。通过改变外交联剂用量，调控所得材料的比表面积和孔径；探索实现编织微孔聚合物网络有序性的可行方案。同时，所得材料在多相催化及光电领域的应用也将纳入本项目的研究体系内。研究结果对推进微孔聚合物材料的基础科学研究和实际工业应用具有双重指导意义。
