The pressing need to lower atmospheric carbon dioxide (CO2) concentration has captivated global focus on point-source capture and transformation of this greenhouse gas chemicals. Purpose-driven pore-functionality engineering in metal–organic frameworks (MOFs) can lead high-temperature humid-condition adsorption efficient cycloaddition CO2 further assist achieving unconventional methodologies for sustainable tandem catalysis. Herein, we develop a [Zn2(COO)4N4] building unit-containing chemo-robust framework with carboxamide functionality, free oxygen atoms, π-electron-rich moieties affixed one-dimensional channels. This 3-fold entangled MOF exhibits strong framework–gas interactions unveils variable-temperature recurrent capture–release cycles even under 75% relative humidity. Interestingly, the CO2/N2 selectivity shows remarkable 82% increase an temperature from 273 K (79) 313 (143), which overpowers several porous adsorbents validates potential flue separation. microporous catalyzes solvent-free recyclable various epoxides pressure. In contrast classical Lewis acid-mediated reaction, controlled experiments, including performance comparison urea functionality-truncated isostructural corroborate unique two-point hydrogen bonding-mediated pathway. suitably oriented moiety within channels acts as bond donor (HBD) site deacetalization–Knoevenagel condensation reaction >99% conversion solvent-less mild conditions 4 h. cooperative role acid–base dual sites substrate activation is comprehensively supported by studies using external additives, fluoro-titration-derived interactions, unfunctionalized framework.
