A green and sustainable preparation strategy is critical for the practical applications of microporous organic polymers (MOPs). Here, a new heteropoly acid catalyst/crosslinker system is adopted to prepare a new family of asphalt-based MOPs with a high surface area. In comparison with the conventional Friedel–Crafts hyper-cross-link polymerization, corrosive gases are completely avoided and the employed heteropoly acid catalyst can be recovered with yield up to 95% and recycled at least 9 times, retaining high catalytic performance. Particularly, the low cost, environmentally hazardous asphalt is converted into safe crosslinked polymers with good gas absorption capability. This “killing two birds with one stone” strategy is meaningful for the future industrial practice.

杂多酸催化制备沥青基微孔有机聚合物

绿色和可持续的制备策略对于微孔有机聚合物（MOP）的实际应用至关重要。在这里，采用了一种新的杂多酸催化剂/交联剂体系来制备具有高表面积的新的沥青基MOP系列。与常规的Friedel-Crafts超交联聚合相比，完全避免了腐蚀性气体，并且所用杂多酸催化剂的回收率最高可达到95％，并且至少循环使用9次，从而保持了较高的催化性能。特别地，低成本，对环境有害的沥青被转化为具有良好气体吸收能力的安全的交联聚合物。这种“用一块石头杀死两只鸟”的策略对未来的工业实践意义重大。
