本文报道了一种高效的碘吸附剂，通过合理设计多孔偶氮桥接卟啉酞菁网络（AzoPPN），该网络由游离碱5,10,15,20-四（4-硝基苯）卟啉和四氨基酞菁镍进行无催化剂偶联反应合成。AzoPPN具有永久性的多孔结构，骨架中有大量的卟啉和酞菁单位作为有效的吸附位点。它对高达290 wt.%的碘蒸气有很好的吸附作用，对溶液中的碘也有很好的吸附剂性能。这种在一种吸附剂中结合物理吸附和化学吸附的策略将为开发新的碘捕获材料铺平道路。
We report a highly efficient iodine adsorbent achieved by rational design of a porous azo-bridged porphyrinphthalocyanine network (AzoPPN), which was synthesized by a catalyst-free coupling reaction between free-base 5,10,15,20-tetrakis(4-nitrophenyl)-porphyrin and nickel tetraaminophthlocyanine. AzoPPN has a permanent porous structure and plenty of porphyrin and phthalocyanine units in the skeleton as effective sorption sites. It displays excellent adsorption of iodine vapor up to 290 wt.% and also shows remarkable capability as adsorbent for iodine in solution. This strategy of combining physisorption with chemisorption in one adsorbent will pave the way for the development of new materials for iodine capture.
