Abstract：

Visible-light　active,　heterogeneous,　and　organic　photocatalysts　exhibit　a　more　sustainable　and　environmentally　friendly　alternative　to　classical　metal-based　catalysts.　Two-dimensional　covalent　organic　frameworks　(2D-COFs)　with　permanent　porosity,　columnar　π-arrays　and　excellent　stability,　that　can　become　an　excellent　platform　for　heterogeneous　photocatalysis　of　organic　transformations.　Here　we　report　a　predesigned　imine-based　COF　with　electron　donor　and　acceptor　structure.　And　new　framework　possesses　large　surface　area,　high　crystallinity,　outstanding　stability　and　broad　absorption　range　in　the　visible-light　region　as　well　as　good　photoelectric　response　characteristics.　Importantly,　it　was　found　to　be　a　highly　effective　heterogeneous　photocatalyst　for　reductive　dehalogenation　of　phenacyl　bromide　derivatives　and　α-alkylation　of　aldehydes　under　irradiation　of　visible-light.　In　addition,　the　COF　gave　good　recyclability　and　could　be　reused　after　a　simple　separation　manipulation.　The　current　present　still　reveals　a　great　prospect　for　2D-COFs　as　metal-free,　heterogeneous　photocatalysts　for　organic　transformations.　©　2018　Elsevier　B.V.
