Amino, bromo, nitro, and naphthalene functionalized UiO-66 metal-organic frameworks have been synthesized through reticular chemistry. UiO-66-NH(2) is shown to be suitable for postsynthetic modification with a variety of anhydrides to generate new, functionalized frameworks.

Bimetallic MOF Photocatalysts Ti atoms rapidly replace Zr in UiO-66-NH2 crystal under microwave irradiation. The formed congenetic “shell-core” structure and the introduced electron acceptor, Ti, enhance photocatalytic nitric oxide (NO) removal. Furthermore, synergy of NO photooxidation subsequent NO2 adsorption not only removes efficiently an environmentally friendly fashion, but also provides...

We report on the successful functionalization of cotton fabrics with a water-stable metal-organic framework (MOF), UiO-66, under mild solvothermal conditions (80 °C) and its ability to adsorb and degrade water micropollutants. The functionalized cotton samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), transmiss...

Thin films of stable metal-organic frameworks (MOFs) such as UiO-66 have enormous application potential, for instance in microelectronics. However, all-gas-phase deposition techniques are currently not available for such MOFs. We here report on thin-film deposition of the thermally and chemically stable UiO-66 in an all-gas-phase process by the aid of atomic layer deposition (ALD). Sequential r...

We report a practical approach, the first of its kind, to construct nanoscale UiO-type metal-organic framework (Mi-UiO-66 and Mi-UiO-67) fluorescent probes for the detection of Cys and GSH. They showed high sensitivity (10(-11) M) and selectivity for Cys and GSH, and their fluorescence imaging of Cys and GSH in living cells was well demonstrated.

Semiconductor photocatalysis is a novel highly efficient and low-cost method for removing organic pollutants from wastewater. However, the photoreduction performance of semiconductors on limited due to weak absorption visible light caused by its wide band gap low carrier utilization rate resulting severe electron-holes recombination. In present study, flower-like NH2-UiO-66 (NU66)/ZnO nanocompo...
