This paper reports the design and facile synthesis of porous polynorbornenes containing a 4,4′-dialkoxy-azobenzene subunit (named Azo-POP-13 and Azo-POP-14). They were synthesized by the robust reductive azo-coupling polymerization of the Ring-Opening-Metathesis-Polymerization (ROMP) product on bis-para-nitrophenylether of the norbornene diol. The polymerization rate of exo-NBNPE (k_app = 18.7 × 10⁻² s⁻¹) is faster than that of endo-NBNPE (k_app = 3.64 × 10⁻² s⁻¹). The as-synthesized Azo-POP-13 was found to selectively adsorb 4-nitrophenol (4-NP) over 4-aminophenol (4-AP) in water, with a selectivity up to 14.6 and good recyclability.

带有偶氮苯亚基的多孔聚降冰片烯的简便合成：水中4-氨基苯酚上4-硝基苯酚的选择性吸附

本文报道了含有4,4'-二烷氧基-偶氮苯亚基（分别称为Azo-POP-13和Azo-POP-14）的多孔聚降冰片烯的设计和合成。他们由开环复分解聚合（ROMP）的产品对双-鲁棒还原偶氮偶合聚合来合成对降冰片烯二醇-nitrophenylether。exo -NBNPE（k _app = 18.7×10 ^-2 s ^-1）的聚合速率快于内-NBNPE（k _app = 3.64×10 ^-2 s ^-1））。发现合成后的Azo-POP-13在水中比4-氨基苯酚（4-AP）选择性吸附4-硝基苯酚（4-NP），选择性高达14.6，并且具有良好的可回收性。
