Facilely synthesized Eu3+ post-functionalized UiO-66-type metal-organic framework for rapid and highly selective detection of Fe3+ in aqueous solution

Eu3+-Postdoped UIO-66-Type Metal–Organic Framework as a Luminescent Sensor for Hg2+ Detection in Aqueous Media

“…The photoelectron line of Eu 3d 5 at 1135.18 eV is observed in Figure 4, which indicates the presence of Eu 3+ in the MOFs. 31 The photoelectron line at 400.28 eV corresponds to the N 1s spectra, which indicates the presence of a pyridine ring. 35 Besides, the binding energies of O 1s and N 1s are moved from 531.21 to 531.33 eV and from 400.76 to 400.28 eV, respectively.…”

“…In Figure S2, the morphology of UIO-66(DPA) is similar to that of UIO-66; this indicates that a moderate amount of DPA did not change the structure of the UIO-66 MOF. 30,31 Moreover, the morphology of Eu 3+ -modified UIO-66(DPA) is also similar to that of UIO-66. These results coincide with the changes of XRD.…”

Amino-Functionalized Al–MOF for Fluorescent Detection of Tetracyclines in Milk

“…Among these fluorescent materials, FMOFs are widely explored owing to their intriguing spectral characteristics as well as infinite tenability, excellent thermal stability, availability of in-pore functionality, and outer-surface modification . As chemosensors, hitherto FMOFs have been intensively developed to detect various targets, e.g., metal ions, small molecules, gases, biomarkers, pH values, and temperatures . The fluorescent properties of FMOFs generally have a strong response to their crystalline structures and coordination environment of metal centers and their interactions with guest species (for example, coordination and hydrogen bonds, π–π interactions), which provide solid rationale for fluorescent sensing .…”

Bifunctional color-tuning luminescent Ln@Zr-MOFs for white LEDs and sensitive, ultrafast detection of nitrobenzene in aqueous media

“…The main diffraction peaks at 7.36°, 8.45°, 14.76°, 25.80°, and 30.78° of the obtained UiO-66 are in good agreement with the simulated results of the single-crystal structure, proving the successful synthesis of UiO-66 in our work. 25,26 Furthermore, Zr-MOFs and Ln@Zr-MOFs exhibit the same structure and high purity as UiO-66 with narrow and sharp diffraction peaks. This indicates that the structure of MOFs is not changed after the ligand replacement and the introduction of Ln 3+ .…”
