Dichromate　is　known　for　severe　health　impairments　to　organisms.　New　and　valid　strategies　have　been　developed　to　rapidly　detect　and　efficiently　remove　this　pollutant.　Constructing　stable　luminescent　metal-organic　frameworks　(MOFs)　for　dichromate　recognition　and　removal　from　aqueous　solution　could　provide　a　feasible　resolution　to　this　problem.　Herein,　a　new　luminescent　Zr(IV)MOF,　Zr6O4(OH)(7)(H2O)(3)(BTBA)(3)　(BUT-39,　BUT　=　Beijing　University　of　Technology)　was　constructed　through　the　reaction　of　a　newly　designed　functionalized　T-shaped　ligand　4,4＇,4＂-(1Hbenzo[d]imidazole-2,4,7-triyl)tribenzoic　acid　(H(3)BTBA)　with　zirconium　salt.　BUT-39　has　a　unique　porous　framework　structure,　in　which　Zr-6　cluster　acts　as　a　rare　low-symmetric　9-connected　node　and　BTBA(3-)　as　a　T-shaped　3-connected　linker.　As　far　as　we　know,　this　represents　the　first　case　of　a　(3,9)-connected　Zr(W)-MOF.　BUT-39　could　retain　its　framework　integrity　in　boiling　water,　2　M　HCI　aqueous　solution,　and　pH　12　NaOH　aqueous　solution.　Due　to　its　good　water　stability　and　strong　fluorescent　emission,　BUT-39　is　then　employed　in　fluorescence　sensing　for　various　ions　in　aqueous　solution　and　shows　good　performance　toward　Cr2O72-　selectively,　at　a　low　concentration　and　a　short　response　time　(＜1　min).　Simultaneously,　it　also　exhibits　excellent　capacity　to　rapidly　capture　Cr2O72-　(within　1　min)　with　a　high　uptake　up　to　1　mmol　g(-1).　Taking　advantage　of　its　excellent　stability,　sensitive　and　selective　sensing,　as　well　as　rapid　and　high　adsorption,　BUT-39　is　expected　to　be　useful　in　Cr2O72-　detection　in　and　removal　from　water.
