A novel porous polymer, denoted as tetraphenylethene-based porous polymer (PTPEK), was synthesized via a catalyst-free C–O coupling reaction. The unique combination of dipole-π interactions and π-π interactions within PTPEK facilitated exceptional adsorption property towards trinitrotoluene (TNT). Furthermore, the incorporation of tetraphenylethene groups, which exhibit aggregation-induced emission (AIE) activity, endowed PTPEK with remarkable TNT detection capability. Simultaneously, PTPEK showed excellent selective adsorption capability and outstanding selective fluorescence detection performance for TNT. At room temperature (298 K), PTPEK demonstrated a maximum TNT adsorption capacity of 209.2 mg g⁻¹, reaching 65 % of its adsorption equilibrium within just 1 h. Additionally, PTPEK exhibited a rapid quenching time of 125 s for TNT, with a low detection limit of 4.56 × 10⁻⁶ mol/L. Notably, PTPEK also displayed excellent recyclability characteristics.

通过无催化剂的C-O偶联反应合成了一种新型多孔聚合物，称为四苯乙烯基多孔聚合物（PTPEK）。PTPEK 内偶极-π 相互作用和 π-π 相互作用的独特组合促进了对三硝基甲苯 (TNT) 的卓越吸附性能。此外，四苯乙烯基团的掺入具有聚集诱导发射（AIE）活性，赋予 PTPEK 卓越的 TNT 检测能力。同时，PTPEK对TNT表现出优异的选择性吸附能力和出色的选择性荧光检测性能。在室温（298 K）下，PTPEK 对 TNT 的最大吸附容量为 209.2 mg g ⁻¹，在短短 1 小时内达到其吸附平衡的 65%。此外，PTPEK对TNT表现出125 s的快速猝灭时间，检测限低至4.56 × 10 ^-6  mol/L。值得注意的是，PTPEK 还表现出优异的可回收特性。
