Crystal structure and luminescent properties of [1-(biphenyl-4-yl)-1H-imidazole-κN (3)]di-chloridozinc

The mononuclear title compound, [ZnCl2(C15H12N2)2], was synthesized by reaction of zinc chloride and 1-(biphenyl-4-yl)-1H-imidazole (bpi) under hydro-thermal conditions. The Zn(II) atom is tetra-hedrally coordinated by the free imidazole N atoms of two bpi ligands and by two Cl atoms. The bpi ligands are not planar, with dihedral angles of 37.52 (14) and 42.45 (14)° between the phenyl rings and 37.13 (14) and 40.05 (14)° between the phenyl rings and the attached imidazole rings, respectively. Mutual π-π inter-actions, with a centroid-to-centroid distance of 3.751 (2) Å between the phenyl and imidazole rings of neighbouring ligands, are present, leading to dimers that are arranged in rows parallel to [-211].

Regulation of the pore size by shifting the coordination sites of ligands in two MOFs: enhancement of CO2 uptake and selective sensing of nitrobenzene

Two MOFs were constructed using azine functionalized and pyridyl based neutral ligands along with a V-shaped sdb linker, and exhibit highly efficient luminescence sensing for nitrobenzene and sorption selectivity for CO₂ over CH₄.

Metal–organic frameworks based on flexible ligands (FL-MOFs): structures and applications

This review presents the recent developments on FL-MOFs, including their structures and applications in gas adsorption, catalysis and proton conduction.

Synthesis, characterisation, water adsorption and proton conductivity of three Cd(ii) based luminescent metal–organic frameworks

Three Cd(ii) based H-bonded 3D MOFs show a significant amount of uptake for water vapor and an impedance measurement indicates that they show proton conductivity at a higher temperature (358 K) at 95% relative humidity.
