Poly(4-vinylpyridine-co-divinylbenzene) polyHIPE was prepared with 80% porosity and a typical cellular interconnected topology. Up to 25% of 4-vinylpyridine (VP) was introduced into polymer. PolyHIPE was additionally crosslinked (hypercrosslinked) via the post polymerisation radical treatment and an increase of specific surface area was observed. New polymer was functionalized via the loading of copper (II) and it was demonstrated that it can be efficiently used as a solid supported catalyst for the azomethine imine-alkyne cycloaddition click reaction. A cycloadduct of bimane analogue was formed in high yield and purity.
