Nanoporous polymers from cross-linked polymer precursors via tert-butyl group deprotection and their carbon dioxide capture properties

<p>A two-step synthetic strategy has been developed to achieve functionalized nanoporous polymers via the deprotection of the cross-linked polymer precursors containing <i>tert</i>-butyl carboxylate-functionalized stilbene or styrene and <i>N</i>-phenylmaleimide alternating sequences. Three different deprotection methods to generate nanoporosity were examined in this work. The resulting nanoporous polymers showed a significant increase in BET surface area. The effects of cross-linking density and the stiffness of the alternating sequences on the nanoporosity of these polymers were studied. The resulting nanoporous polymers were also investigated as potential CO₂ sorbents.</p>
