“…[31][32] These transformed MOFs have given a range of catalyst in the field. [33][34] By altering the basic MOF structure, functionalities are introduced to the MOFs, hence MOF can also be seen as a support for the active site for catalysis. 35 Another advantage of MOF as a catalyst is that it is used as a heterogeneous catalyst and gives the opportunity to be reused to multiple times, under right regeneration conditions.…”

“…The coordination connection can be achieved by introducing a simple metal atom or organic linker. Alkali metals have abundant coordination modes, which can effectively connect a variety of components, including ligands, clusters, and macromolecular compounds, and may be used to connect adjacent uranyl ions. − The alkali metal is connected to the oxygen of the carboxyl groups and can form a multi-metal oxygen cluster with uranyl. In the MOF structure, there is no longer a single metal atom as a metal node connecting framework, but the metal oxygen cluster bridges the organic ligands to form the framework.…”

The stability of many MOFs is not satisfactory, which severely limits the exploration of their potential applications. Given this, we have proposed a strategy to improve the stability of MOFs by introducing alkali metal K+ capable of coordinating with metal nodes, which finally induces the interpenetrating uranyl-porphyrin framework to connect as a whole (IHEP-9). The stability experiments reveal that the IHEP-9 has good thermal stability up to 400 °C and can maintain its crystalline state in the aqueous solution with pH ranging from 2 to 11. The catalytic activity of IHEP-9 as a heterogeneous photocatalyst for CO2 cycloaddition under the driving of visible light at room temperature is also demonstrated. This induced interpenetration and fixation method may be promising for the fabrication of more functional MOFs with improved structural stability.

“…The intense signals observed at 1716–1236 cm –1 are attributed to the ν(CO), ν(CC), ν(NN), and ν(CN) stretching vibrations of DMA solvent molecules, benzene rings, and tetrazole units . Significantly, it is difficult to distinguish the contributions of tetrazole units and benzene rings as a result of their coexistence . Additionally, the characteristic peaks located at 1209–424 cm –1 can be attributed to δ(C–H) bending vibrations, as well as ν(N–N), ν(C–C), and ν(C–N) stretching vibrations .…”

Tetrazole-Containing Triphenylamine-Based MOF as a Sensitive Sensor for Food Inspection

A new metal–organic framework (MOF) with tetrazole-derived triphenylamine (TPA) as the ligand, namely Mn–TPA, has been successfully prepared and thoroughly characterized via thermogravimetric analysis, IR spectroscopy, elemental analysis, UV–vis absorption, fluorescence analysis, bond valence sum calculations, and single-crystal and powder X-ray diffraction analysis. The undulating monolayer of Mn–TPA can hinder the interaction and tight stacking among analytes, which creates a bionic microenvironment for the electrochemical recognition process. Mn–TPA exhibits high specific surface area, stable film-forming capacity, excellent electrochemical activity, and good biocompatibility. Furthermore, the developed Mn–TPA-based immunosensing system exhibits an excellent limit of detection of 0.50 pg·mL–1 toward vomitoxin, which is more outstanding than that of the reported vomitoxin-sensing system. Thus, this work shows the great potential of a well-designed MOF as an easy-to-make and highly sensitive electrochemical platform for biosensing in food safety detection and other fields.
