Porous materials as adsorbents with high affinities to target molecules have great potential to facilitate environmentally important separations and remediation. One key challenge is to keep a reactive functionality inert while building a super structure. Protection or post-modification methods are limited because of the incomplete activation, and often require harsh conditions that also compromise the framework integrity. We recently used (<i>Chem. Mater.</i> 28 (16), 5592–5595, 2016) a metal-free, one-pot, RT, deprotection-coupling, regioselective reaction for the first time to synthesize a porous network with high specific surface area (1035 m<sup>2</sup>/g) and easy post-functionalization. The obtained microporous polymer is a robust C-C bonded structure with alkyne and perfluorinated moieties. Aromatic fluorines readily undergo nucleophilic substitutions facilitating numerous post-modification possibilities, a particular feature that was not previously available.
