[3+3] Imine and β-ketoenamine tethered fluorescent covalent-organic frameworks for CO2 uptake and nitroaromatic sensing

Two imine and β-ketoenamine linked [3+3] robust, porous and fluorescent covalent-organic frameworks, synthesized by solvothermal methods, have been found to be efficient for CO₂ capture and detection of polynitroaromatic compounds.
