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-paranitrophenylether of the norbornene diol. The polymerization rate
of exo-NBNPE (kapp = 18.7 × 10?2 s?1) is faster than that of endo-NBNPE (kapp = 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.
