“…MOFs’ structural and dynamic features, such as crystallinity, porosity, and tunability, can be designed to fill the gap between zeolites and surface metal-organic catalysts. These materials cover a much wider range of pore sizes than zeolites; thus, they possess a substantial potential to be used as great heterogeneous catalysts [ 6 , 7 , 8 , 9 ].…”

A chromium-containing metal-organic framework (MOF), MIL-101 (Chromium(III) benzene-1,4-dicarboxylate), was used to catalyze the one pot, three component synthesis of some 2,4,5-trisubstituted imidazoles under solvent-free conditions. The advantages of using this heterogeneous catalyst include short reaction time, high yields, easy and quick isolation of catalyst and products, low amount of catalyst needed, and that the addition of solvent, salt, and additives are not needed. This catalyst is highly efficient and can be recovered at least 5 times with a slight loss of efficiency. The structure of the metal-organic frameworks (MOF) was confirmed by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (HNMR) were performed to confirm some of the synthesized products. Experimental data indicated that the optimum amount of catalyst was 5 mg for benzil (1 mmol), 4-chlorobenzaldehyde (1 mmol), and ammonium acetate (2.5 mmol), and the synthetic route to the various imidazoles is performed in 10 min by 95% yield, an acceptable result rivalling those of other catalysts.

A water-stable lanthanide metal-organic framework for fluorimetric detection of ferric ions and tryptophan

et al. 2017

The preparation of a highly water stable and porous lanthanide metal-organic framework (MOF) nanoparticles (denoted SUMOF-7II; SU refers to Stockholm University) is described. SUMOF-7II was synthesized starting from the tritopic linker of 2,4,6-tri-p-carboxyphenyl pyridine (H3L2) and La(III) as metal clusters. SUMOF-7II forms a stable dispersion and displays high fluorescence emission with small variation over the pH range of 6 to 12. Its fluorescence is selectively quenched by Fe(III) ions compared to other metal ions. The intensity of the fluorescene emission drops drops linearly in 16.6–167 μM Fe(III) concentration range, and Stern-Volmer plots are linear. The limit of detection (LOD) is 16.6 μM (at an S/N ratio of >3). This indicator probe can also be used for selective detection of tryptophan among several amino acids. Compared to the free linker H3L2, SUMOF-7II offers improved sensitivity and selectivity of the investigated species. Graphical abstractA water-stable porous lanthanide metal-organic framework SUMOF-7II (La) has shown to be an excellent probe for the detection of ferric ions among other metal ions, and tryptophan among other amino acids in aqueous solution. The new probe displays high and stable fluorescence signal in a wide pH range (6–12).

“…Therefore a sensitive and effective CL sensor has been employed for the sensing of each H 2 O 2 or Ppi. [66] Li and co-workers in 2019 discovered a Co(II)-based MOF material having peroxidase-mimic activity. These are capable of catalysing the CL reaction between luminol and H 2 O 2 and could augment the CL signal substantially.…”

This review intends to encapsulate the advanced developments in the field of sensors based on MOF materials. MOFs possess structural tunability and vast surface area, which are vital for the development of efficient sensors. The energy transfer schemes within the frameworks and their light-harvesting capacity make MOFs functional, active and integral components in MOF-based devices. Their chemically tunable frame-work with precise host-guest interactions performs a significant role in specific sensing of biomolecules, small organic molecules and metal ions. Depending on the signal transduction schemes, four major classes of MOF-based sensing devices have been outlined. Also, the significant challenges and restrictions of this research field have been discussed.
