Metal–organic framework structures of fused hexagonal motifs with cuprophilic interactions of a triangular Cu(i)₃(pyrazolate-benzoate) metallo-linker

Abstract

The reaction of the N,O-heteroditopic bifunctional ligand 4-(3,5-dimethyl-1H-pyrazol-4-yl)benzoic acid (H2mpba) with Cu(NO3)2·2.5H2O and Zn(NO3)2·4H2O or Zn(CH3COO)2·2H2O in N,N-dimethylformamide (DMF) results in concomitant formation of three bimetallic metal-organic frameworks (MOFs) with...

Deep core level hard X‐ray photoelectron spectroscopy for catalyst characterization

“…Many works have been already published on the application of Auger peaks and Auger parameter for the description of metal properties in MOFs. [48][49][50][51] Moreover, adsorption, stability, and framework dynamics in MOFs are key parameters for catalysis, and understanding the ligand effect (also in terms of polarization effects) is crucial. 52,53 In this context, comparison of reference MOFs with others with modified ligands can become an important tool for correlating theory, chemical-physical properties (e.g., polarizability, ligand modifications) and catalytic response.…”

“…An important application of this approach would be related to catalysts presenting a wide variety of ligands. Many works have been already published on the application of Auger peaks and Auger parameter for the description of metal properties in MOFs 48–51 . Moreover, adsorption, stability, and framework dynamics in MOFs are key parameters for catalysis, and understanding the ligand effect (also in terms of polarization effects) is crucial 52,53 .…”

A 3D/3D hetero-interpenetrated MOF with a novel (3,9)-c net and 6-c lcy net for the fluorescence detection of carbaryl

“…To date, only four examples of two-fold 3D/3D hetero-interpenetrated nets with different topologies in the field of MOFs have been reported. [14][15][16][17] To investigate the permanent porosity of 1, the N 2 reversible type-I isotherm was observed at 77 K, which is characteristic of a microporous material. (Fig.…”
