We report a multigram synthesis of new, robust, insoluble porous organic polymers based on the semiconducting platform of hexamethyltruxene (TxPPs and TxBnPPs) which present high Brunauer–Emmett–Teller (BET) specific surface areas (1710–1186 m2 g−1). These new polymers exhibit high thermal and chemical stability and can be easily postfunctionalized under different reaction conditions, allowing the incorporation of acid, base or acid–base groups (TxPPs-SO3H, TxPPs-NH2 and TxPPs-SO3H–NH2) in the polymeric networks, yet displaying a significant porosity. The potential applications of the new truxene-based polymers as heterogeneous catalysts are also presented. The intrinsic photocatalytic activity of the truxene network which takes advantage of the semiconducting character of the constituent units is investigated in the aerobic oxidative self-coupling of benzylamine under visible light. On the other hand, the use of these polymers as heterogeneous supports is investigated by studying the catalytic behavior of the monofunctional acid or bifunctional acid–base polymers in esterification and transesterification and one-pot cascade reactions, respectively.

x烯基多孔聚合物:从合成到催化活性

我们报告了基于六甲基甲苯(TxPPs和TxBnPPs)半导体平台的新型,坚固,不溶性多孔有机聚合物的多克合成,该聚合物具有较高的Brunauer-Emmett-Teller(BET)比表面积(1710-1186 m 2 g -1) 。这些新型聚合物具有很高的热稳定性和化学稳定性,可以在不同的反应条件下轻松地进行后官能化,从而可以引入酸,碱或酸碱基团(TxPPs-SO 3 H,TxPPs-NH 2和TxPPs-SO 3 H-NH 2个)在聚合物网络中,但仍显示出显着的孔隙率。还介绍了新的基于丁烯的聚合物作为非均相催化剂的潜在应用。利用可见光下苄胺的好氧氧化自偶联研究了利用组成单元的半导体特性的丁烯网络的固有光催化活性。另一方面,通过研究单官能酸或双官能酸基聚合物分别在酯化和酯交换和一锅级联反应中的催化行为,研究了将这些聚合物用作非均相载体。
