摘要

在聚合物中加入具有独特结构和性能的大环可以增加聚合物与污染物之间相互作用位点的数量和特异性，从而提高对污染物的吸附潜力。本研究介绍了一种由柱状[5]芳烃衍生物（10BrP5）作为电子受体和三（4-（吡啶基-4）苯基）胺（TPPA）作为电子供体的卤素键相互作用形成的超分子聚合物。所得的超分子聚合物10BrP5-TPPA（简称10BPTP）表现出优异的碘捕获能力，以1.57 g g - 1 h-1的速率去除挥发性碘，并以2.7 × 10-2 g mg-1 min-1的动力学速率从溶液中快速捕获碘。该方法利用卤素键合的独特性质，构建了一种稳定的高效吸附碘的功能材料，为碘吸附剂的未来发展提供了有价值的见解。

Halogen Bonding-Driven Supramolecular Polymers Based on Pillararenes for Efficient Iodine Capture

Incorporating macrocycles with unique structures and properties into polymers can increase the number and specificity of interaction sites between the polymer and pollutants, thereby enhancing the potential for pollutant adsorption. This study introduces a supramolecular polymer formed by halogen bonding interactions between a pillar[5]arene derivative (10BrP5) as an electron acceptor and tris(4-(pyridinyl-4)phenyl)amine (TPPA) as an electron donor. The resulting supramolecular polymer, 10BrP5-TPPA (10BPTP for short), shows exceptional iodine capture capabilities, removing volatile iodine at a rate of 1.57 g g^–1 h^–1 and rapidly capturing iodine from solution with a kinetic rate of 2.7 × 10^–2 g mg^–1 min^–1. This approach leverages the unique properties of halogen bonding to construct a stable and functional material for efficient iodine adsorption, offering valuable insights for the future development of iodine adsorbents.
