Abstract
A new Zn based polyrotaxane 3D metal-organic framework (MOF), {[Zn3(BTC)2(Bimb)3.5][Zn(HCOO)(Bimb)1.5]·CH3COO·2(CH3)2NH·2DMF·9H2O}n (KA@MOF-S2)(Bimb = 1,4-bis[(1H-imidazol-1-yl)methyl]benzene, BTC3‒ = 1,3,5-benzenzetricarboxylate) has been synthesized under solvothermal conditions. Single-crystal X-ray diffraction analysis reveals that KA@MOF-S2 exhibits a novel 1D + 3D → 3D interpenetratedPolyrotaxane MOF architecture. KA@MOF-S2 possesses a new 3,3,3-c net 3-nodal interpenetrated network with (122.14)(8.122)(83)2 topology. KA@MOF-S2 can be used as a selective fluorescence sensing material for the quantitative detection of VOCs (Acetone, NB), antibiotic (NFT) and biomolecules (UA, sucrose) and photocatalytic degradation of Rose Bengal (RB) and Congo Red (CR) dye under sun-light irradiation.
