A new fluorescent hybrid porous polymer (HPP) is synthesized by an anhydrous FeCl -mediated oxidative coupling reaction of octa[4-(9-carbazolyl)phenyl]silsesquioxane (OCPS). The polymer possesses a surface area of 1741 m g and hierarchical bimodal micropores (1.41 and 1.69 nm) and mesopores (2.65 nm). The material serves as an excellent adsorbent for CO and dyes with high adsorption capacity for CO (8.53 wt %,1.94 mmol g ), congo red (1715 mg g ) and rhodamine B (1501 mg g ). In addition, the presence of peripheral cabozolyl groups with extended π-conjugation in the crosslinked framework imparts luminescent character to the polymer and offers the detection of nitroaromatic compounds.
一种新型荧光杂化多孔聚合物（HPP）是通过无水 FeCl3 介导的八[4-（9-咔唑基）苯基]倍半硅氧烷（OCPS）的氧化偶联反应合成的。该聚合物具有 1741 m2/g 的表面积和分级双模态微孔（1.41 和 1.69nm）和中孔（2.65nm）。该材料可用作 CO 和染料的优良吸附剂，对 CO 的吸附容量高（8.53wt%，1.94mmol/g）、刚果红（1715mg/g）和罗丹明 B（1501mg/g）。此外，交联骨架中具有扩展π共轭的外围咔唑基赋予聚合物发光特性，并提供对硝基芳烃化合物的检测。
