Covalent　organic　frameworks　(COFs)　are　appealing　for　electrochromic　(EC)　application　due　to　their　designable　redox-active　building　blocks,　ordered　porous　structure,　and　well-developed　π-π　stacking　structure,　which　greatly　enhance　the　generation　and　transportation　of　carriers　for　EC　switching.　However,　such　EC　COFs　are　rare　and　still　dominated　by　two-dimensional　network　topology　till　now.　Herein,　a　bis(triphenylamine)-based　one-dimensional　(1D)　COF,　termed　as　TAPD-TDA　COF,　was　reported　and　the　EC　performance　of　the　COF　film　directly　grown　on　indium　tin　oxide　(ITO)　coated　glass　was　systematically　studied.　Theoretical　and　experimental　results　indicated　that　TAPD-TDA　COF　possessed　1D　covalent　and　π-π　stacking　structure,　with　comparatively　high　crystallinity　and　Brunauer-Emmett-Teller　surface　area.　Furthermore,　the　characterization　of　the　oriented　COF　film　demonstrated　that　the　film　on　ITO　glass　was　uniform　and　exhibited　reversible　color　transition　between　bright　yellow　and　light　grey　during　the　applied　cyclic　potentials.　Significantly,　in　the　redox　process,　it　displays　remarkable　absorption　spectral　changes　in　the　near-infrared　region,　which　is　ascribed　to　the　active　degree　of　intervalence　charge　transfer　(IVCT)　effect　between　bis(triphenylamine)　cation　radicals　within　the　COF　skeleton.　The　absorption　wavelength　of　the　COF　film　linearly　shifts　between　1060　and　940　nm　with　the　applied　potentials.　Undoubtedly,　this　work　on　a　novel　1D　COF　might　shed　light　on　further　exploration/application　in　smart　optoelectronic　materials.　©　2022　Elsevier　B.V.
