As well known, Zr-based UiO-type MOFs exhibit extraordinary high thermal and chem. stability, making them excellent candidates for new kinds of host materials. In this work, A UiO-67 type MOF (UiO-67-PO) has been successfully synthesized based on a lanthanide-affinity pyridin-4(1H)-one decorated dicarboxylate ligand. Post-functionalization with Tb3+ and Eu3+ (Tb1-x/Eux@UiO-67-PO, x = 0 to 1.0) afforded tunable green ↔ yellow ↔ red light-emitting materials. Tb@UiO-67-PO shows strong luminescence and water stability, which can be served as an efficient multi-sensor for detection of aniline, Cr2O2-7 and Fe3+ ions in aqueous solution with low detection limit of 60.11, 0.33 and 12.69 μM, resp. This study displays the advantages of combining luminescent lanthanide ions with robust UiO-type MOFs in tuning the fluorescence and sensing performance. In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2Application In Synthesis of Pyridin-4-ol).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Application In Synthesis of Pyridin-4-ol
