Three　porous　lanthanide　metal-organic　frameworks　(Ln-MOFs)　[Ln(BCB)(DMF)]center　dot(DMF)(m)(H2O)　(Ln　=　Yb3+　(1),　E-r3+　(2),　Dy3+　(3),　DMF　=　N,N＇-dimethylformamide)　have　been　successfully　prepared　using　4,4＇,4＂-benzenetricarbonyltribenzoic　acid　(H3BCB)　as　organic　linkers.　X-ray　diffraction　analysis　reveals　that　these　ketone　group　decorated　complexes　are　isostructural,　and　each　form　a　three-dimensional　structure　possessing　two　types　of　one-dimensional　channels　along　the　c　axis.　Moreover,　the　near-infrared　luminescence　properties　of　the　three　complexes　were　also　investigated.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
