Abstract：

A　novel　covalent　organic　framework　(COF)　(Tp-BI-COF)　with　combined　ketimine-type　enol-imine　and　keto-enamine　linkages　was　prepared　through　a　cascade　of　ketimine　condensation　followed　by　aldimine　condensation　and　characterized　by　XRD,　solid　state　13C　NMR,　IR,　TGA　and　BET.　Tp-BI-COF　showed　high　stability　toward　acid,　organic　solvent,　and　boiling　water.　The　2D　COF　exhibited　photochromic　properties　after　being　irradiated　with　a　xenon　lamp.　The　stable　COF,　with　aligned　one-dimensional　nanochannels,　provided　nitrogen　sites　on　pore　walls,　which　confine　and　stabilize　the　H3PO4　in　the　channel　via　hydrogen-bonding　interactions.　After　loading　with　H3PO4,　the　material　showed　excellent　anhydrous　proton　conductivity.　©　2023　The　Royal　Society　of　Chemistry.
