Porous noria polymer: a cage-to-network approach toward a robust catalyst for CO2 fixation and nitroarene reduction

Abstract

The advantages of the cage-to-network design strategy were demonstrated by knitting a waterwheel-like preporous molecular cage, noria, with a rigid aromatic linker to obtain a highly microporous organic polymer (NPOP, S_BET: 748 ± 25 m² g⁻¹). The NPOP was employed for the catalytic conversion of CO₂ to cyclic carbonates under solvent-free reaction conditions. Furthermore, a silver nanoparticle encapsulated NPOP exhibited remarkable catalytic activity for nitroarene reduction with excellent recyclability.
