Tetrazole-based porous metal–organic frameworks for selective CO₂ adsorption and isomerization studies

Abstract

Tetrazole-based porous MOFs and isomers were synthesized for adsorbing carbon dioxide, showing high selectivity.

Ultra-Stable Metal–Organic Framework with Concurrent High Proton Conductivity and Fluorescence Sensing for Nitrobenzene

“…Low-valent metals (soft acid) coordinating with N-containing linkers (soft base) form robust MOFs based on the hard and soft acid–base principle, and Cu­(I)-based complexes possess excellent fluorescence as a result of the d 10 close shell of the Cu­(I) ion, , which benefits the implementation of fluorescence sensing. In addition, tetrazoles and their derivatives are an important class of N-donor ligands and have been well established for achieving porous MOFs, , in which tetrazolate nitrogen atoms, if not bound to metals, can participate in prolific hydrogen bonding with guest water molecules in the pores, which is ideal for constructing superior proton conductors.…”

A {Ni12}‐Wheel‐Based Metal–Organic Framework for Coordinative Binding of Sulphur Dioxide and Nitrogen Dioxide

“…It is a 2‐nodal shp topology with the short (Schläfli) vertex symbol of {4 36 ;6 30 }{4 4 ;6 2 } 3 (Figure 2 e). [27] Four types of twelve‐core clusters have been reported in MOFs, [28–37] and transition‐metal‐cluster‐based MOFs are rarely observed (Figure S3, Table S2). NKU‐100 represents an unprecedented member in this family.…”

Zinc(ii) and cadmium(ii) amorphous metal–organic frameworks (aMOFs): study of activation process and high-pressure adsorption of greenhouse gases

“…Due to the presence of an electron-deficient carbon atom, carbon dioxide is expected to interact with protic electronegative functional groups, leading to strong chemisorption. This simple interaction has so far led to a number of nanoporous polymers in which nitrogen-rich functions are incorporated, such as triazine, 65,66 tetrazole, 67 imidazole, 68,69 imide 70 and amines. 42,71 Increased CO 2 adsorption capacity in UPJS-13 (FD) and UPJS-14 (FD) can be explained by an interaction between CO 2 molecules and adsorption sites represented by a lone pair on the azo functional groups located in the molecular structure of the MTA linker.…”
