Poly{tris[4-(2-thienyl)phenyl]amine} (PTPATTh) and poly[tris(4-carbazoyl-9-yl phenyl)amine] (PTPATCz) are thiophene-based and carbazole-based conjugated microporous polymers with triphenylamine as cores. Here we present detailed evidence of highly efficient and iodine capture in both CMPs. Thanks to the propeller-like structure, high porosity, extended π-conjugation and electron-rich characteristics, the both CMPs display efficient, adsorption of I2 in vapor (up to 3.13 and 2.56 g g−1) and in solution. Two ways to release the adsorbed iodine were explored: either slow release into ethanol or quick release upon heating (with a high degree of control). In addition, the both CMPs could be recycled while maintaining 70% iodine uptake capacity (up to 85%). Thus making the resulting CMPs ideal absorbent materials for iodine capture to address environmental issues.

聚{三[4-(2-噻吩基)苯基]胺}和聚[三(4-咔唑基-9-基苯基)胺]共轭微孔聚合物作为吸收剂,可高效吸附碘

聚{三[4-(2-噻吩基)苯基]胺}(PTPATTh)和聚[三(4-咔唑基-9-基苯基)胺](PTPATCz)是基于噻吩和咔唑的具有三苯胺的共轭微孔聚合物作为核心。在这里,我们提供了两种CMP中高效捕获碘的详细证据由于具有螺旋桨状结构,高孔隙率,扩展的π共轭和富电子特性,这两种CMP均显示出有效的I 2在蒸汽中的吸附能力(高达3.13和2.56 g g -1)和解决方案中。探索了两种释放吸附的碘的方法:缓慢释放到乙醇中或加热时快速释放(高度控制)。此外,两种CMP都可以回收利用,同时保持70%的碘吸收能力(高达85%)。因此,使所得的CMPs成为捕获碘以解决环境问题的理想吸收材料。
