Porous covalent organic framework liquid for boosting CO₂ adsorption and catalysis via dynamically expanding effect.

ABSTRACT: The features of intrinsic porosity and fluidity endow porous liquids (PLs) with unique properties and performance but the preparation of PLs remains challenging due to the difficulty in liquefying and keeping porous features at the same time. Herein, we develop a stepwise surface functionalization and ion exchange strategy to achieve a rare example of flexible covalent organic framework (COF)-based PL (COF-PLs). By coating the outer surface of the judiciously selected three-dimensional flexible COF-301 with an imidazolium salt corona, followed by liquefaction using the anion canopy potassium poly(ethylene glycol) sulfonate (PEGS) via electrostatic interactions, a flexible PL, COF-301-PL, can be obtained. Theoretical calculations and CO₂ adsorption experiments reveal that the cav
