A simple solvent- and catalyst-free method is presented for the synthesis of the mesoporous metal-organic framework (MOF) MAF-6 (RHO-Zn(eIm)2) based on the reaction of ZnO with 2-ethylimidazole vapor at temperatures ≤ 100 °C. By translating this method to a chemical vapor deposition (CVD) protocol, mesoporous crystalline films could be deposited for the first time entirely from the vapor phase. A combination of PALS and Kr physisorption measurements confirmed the porosity of these MOF-CVD films and the size of the MAF-6 supercages (diam. ~2 nm), in close agreement with powder data and calculations. MAF-6 powders and films were further characterized by XRD, TGA, SEM, FTIR, PDF and EXAFS. The exceptional uptake capacity of the mesoporous MAF-6 in comparison to the microporous ZIF-8 is demonstrated by vapor-phase loading of a molecule larger than the ZIF-8 windows.

Organic Framework

In this study, a lanthanide metal organic framework based on the ligand of terephthalic acid derived from waste polyethylene terephthalate (PET) bottles was designed and synthesized. The structure and morphology of the Tb-BDC was investigated by X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The Tb-BDC displays a high selectivity and sensitivity towards picric acid (TNP). The luminescence intensities exhibit a linear relation, with a concentration of TNP over the range of 1 × 10−5–1 × 10−4 M, with a limit of detection of 1 × 10−5 M. The sensing mechanism is also discussed. This is the first time that waste PET materials have been used as the starting precursor of terephthalic acid (BDC) for the fabrication of lanthanide MOF (metal organic framework), which is applied in sensing TNP.

A 3D heterometal–organic framework {[TbZn(BPDC)2(HCOO)(H2O)3]·2H2O}n (1) was constructed from Tb3+ and Zn2+ as metal ions and 4,4′-dicarboxylate-2,2′-dipyridine (H2BPDC) as the ligand using a solvothermal method. Single-crystal X-ray diffraction analysis revealed that compound 1 is 2-fold interpenetrating. Thermogravimetric and solvent stability analyses demonstrated that compound 1 displayed good thermal and solvent stabilities. The luminescent explorations revealed that compound 1 exhibited highly sensitive and qualitative detection of nitrobenzene at the ppm level. To our knowledge, the present study reports for the first time the use of an interpenetrating heterometallic metal–organic framework as a luminescent probe for nitrobenzene.
