Abstract:Covalent organic frameworks (COFs) possess good porosity, uniform channels, and tunable skeletons, as well as excellent stability, which are well-suited for gas adsorption. In this study, we developed two pyrazine-based COFs, namely, TFPPz−MPA−COF and TFPPz−BD(OMe) 2 −COF, by condensation reaction of C 4 and C 2 axisymmetric monomers. Both COFs exhibited good crystallinity, well-defined pore structures, and outstanding thermal and chemical stability. TFPPz−MPA−COF and TFPPz−BD(OMe) 2 −COF demonstrated high iod… Show more
