A Noble‐Metal‐Free Porous Coordination Framework with Exceptional Sensing Efficiency for Oxygen

Abstract

Light material: By virtue of the unique framework structure and very high oxygen permeability, a noble‐metal‐free, highly fluorescent, porous coordination polymer demonstrates a rapid, reversible, efficient, stable, and selective fluorescence‐quenching response toward oxygen.

Three d10 metal coordination compounds based on pyrazole-3-carboxylic acid showing mixed-ligand characteristic: Syntheses, crystal structures, and photoluminescent properties

“…Compounds 1-3 show mixed-ligand characteristic: mixed inorganic ligands Cl À and H 2 O and organic ligand Hpac À for 1, mixed organic ligands Hpac À and phen for 2 (also including a discrete inorganic anion ClO 4 À ), and mixed organic ligands pac 2À and 2,2 0 -bipy and inorganic ligand H 2 O for 3. Therefore, compounds 1-3 can serve as examples to study the photoluminescence mechanism of mixed-ligand MOCC systems, especially for that of the mixed-ligand MOCCs with organic and inorganic ligands which are relatively less reported [35][36][37][38][39]. In this work, the photoluminescence properties of 1-3 were explored.…”

“…On the other hand, among the various applications of MOCCs as stated above, the photoluminescence of MOCCs and its related applications [35][36][37][38][39] e.g., the white-light emitter and fluorescence sensor attract more attention from scientists [40][41][42][43][44][45]. Take d 10 Zn(II) and Cd(II) ions for example, they can form coordination geometries varying from tetrahedron, trigonal-bipyramid and square-pyramid to octahedron, hence are suitable for constructing interesting photoluminescent MOCCs with diverse structures [35,36].…”

A self-catenated rob-type porous coordination polymer constructed from triazolate and carboxylate ligands: fluorescence response to the reversible phase transformation

“…[24][25][26] Taking Zn 4 O-based MOFs as an example, when the extendable groups change from carboxylate to azolate ligands, the framework stability in air and moisture conditions can be greatly improved, 27,28 even the defect chemistry of the framework can be well investigated in water.
