A new metal‐organic framework (MOF) compound, [Ni(L)(IDC)(H2O)] ⋅ 0.5 L (1), (H2IDC=4,4′‐iminodibenzoic acid), was synthesized by solvothermal reaction of 2,6‐di(1H‐imidazol‐1‐yl)naphthalene (L) and dicarboxylic acid ligands with nickel salt. The results of single crystal diffraction show that the framework belongs to the P21/c space group and has a unique infinite one‐dimensional (1D) chain structure. They are further linked together through imidazole interaction and finally form a three‐dimensional (3D) structure. The crystal structure was characterized by Powder X‐ray diffraction (PXRD), thermogravimetric analyses (TGA), infrared spectra (IR) and elemental analyses (EA). Meanwhile, the thermal stability and luminescence properties of the crystal were tested. It was found that 1 could recognize acetone molecules by luminescence quenching. It has proved itself an efficient sensor for acetone at low con‐centration.
In this work, a novel metal-organic framework (MOF) based on 2,6-di(1H-imidazol-1-yl)naphthalene (L) and biphenyl-3,4′,5-tricarboxylic acid (H3bptc), namely [Co(L)(Hbptc)(H2O)] (1), has been prepared. 1 has a distinct infinite chain structure, further linked together by winding interactions to give the three-dimensional (3D) network structure. 1 was characterized by X-ray crystallography, infrared spectra (IR) spectroscopy, elemental and thermal analysis. Photoluminescence studies revealed that 1 shows a strong emission at 361 nm upon excitation at 290 nm at room temperature. Moreover, 1 can efficiently detect Fe3+ ions by luminescence quenching.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
