A Zn(II)-based polyrotaxane 1D coordination polymer, {[Zn(Or)(Bimb)(H2O)]2·2H2O}n, 1 (Or = orotate; Bimb = 1,4-bis[(1H-imidazol-1-yl)methyl]benzene), has been synthesized. 1 provides for luminescent sensing of acetone, Fe3+, MnO4–, nitrofurantoin (NFT), uric acid (UA), and sucrose. The coordination polymer displays exceptional intensity quenching of ∼96.1% with 200 mg/dl of sucrose in aqueous solution. In addition, the reactivity of 1 to photocatalytically degrade the organic dye methylene blue (MB), a hazardous organic pigment, was established. 1 was able to degrade the dye due to the generation of reactive oxygen species.

• A new Zn based polyrotaxane 3D metal-organic framework (MOF), {[Zn 3 (BTC) 2 (Bimb) 3.5 ][Zn(HCOO)(Bimb) 1.5 ]·CH 3 COO·2(CH 3) 2 NH·2DMF·9H 2 O} n (KA@MOF-S2) has been synthesized under solvothermal conditions. • KA@MOF-S2 possesses a new 3,3,3-c net 3-nodal interpenetrated network with (122.14)(8.122)(83) 2 topology. • Detection of various concentration of sucrose, 80 mg/dl and 100 mg/dl showed highest 85.6 % and 84.7 % quenching efficiency of KA@MOF-S2. • KA@MOF-S2 can be used as a highly sensitive fluorescence sensing material for the quantitative detection of Acetone, NB, NFT, UA and sucrose. • KA@MOF-S2 showed photocatalytic degradation of Rose Bengal (RB) and Congo Red (CR) dye under sun-light irradiation. A new Zn based polyrotaxane 3D metal-organic framework (MOF), {[Zn 3 (BTC) 2 (Bimb) 3.5 ][Zn(HCOO)(Bimb) 1.5 ]·CH 3 COO·2(CH 3) 2 NH·2DMF·9H 2 O} 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. Synthesised a new KA@MOF-S2 is highly fluorescence sensing material for the quantitative detection of Acetone, NB, NFT, UA and sucrose as well as degradation of RB and CR dye under irradiation.
