Abstract

The pursuit of synthetic routes for design and preparation of nanoporous polymeric networks with inherent permanent microporosity and functionality through bottom-up methodologies remains a driving force in developing CO2-philic materials. We report nanoporous, processable, benzoxazole-linked covalent organic polymers (Box-COPs) that show exceptional thermal stability up to 576 °C. Box-COPs can be formed into films thanks to the silylation that is used to guide polymeric network formation. Surface areas of up to 606 m2 g-1 and narrow pore sizes of 4.36 Å were observed with a CO2 uptake capacity of 139.6 mg g-1 at 273 K and 1 bar. Box-COPs were stable in boiling water for a week without deteriorating CO2 capture capacity.
