Quaterpyridines as Scaffolds for Functional Metallosupramolecular Materials

Abstract

Quaterpyridine (qtpy) ligands have found significant applications as N-heterocyclic scaffolds in self-assembly processes, in particular the formation of various metallosupramolecular architectures, limited, however, by difficulties in their synthesis. Recent progress in the preparative organic and organometallic chemistry of polypyridines has resulted in the elimination of the most serious drawbacks concerning qtpy synthesis, consequently giving rise to a renewed interest in this class of compounds. Herein, we endeavor to define the essential aspects of quaterpyridine chemistry and provide the reader with a perspective on the ways in which this field has begun to flourish.

Photo‐ and Electrochemical Properties of a CO2 Reducing Ruthenium–Rhenium Quaterpyridine‐Based Catalyst

“…The effect of the solvents and the sacrificial agents used are also addressed . To the best of our knowledge, a quaterpyridine (qpy) bridging ligand has not previously been utilised towards intramolecular photocatalytic CO 2 reduction …”

Intrinsic Effect of Pyridine-N-Position on Structural Properties of Cu-Based Low-Dimensional Coordination Frameworks

“…Coordination-driven self-assembly processes harness the directionality and reversibility of metal–ligand interactions to allow formation of supramolecular architectures with strictly defined shape and topology [ 1 , 2 , 3 , 4 , 5 , 6 ]. The spontaneous but controlled generation of well-defined multimetallic architectures is seen in the formation of one-, two- and three-dimensional coordination polymers (CPs) with numerous applications in, e.g., magnetism, molecular separations, dye degradation and catalysis [ 7 , 8 , 9 ].…”

Computational Design of Quaterpyridine‐Based Fe/Mn–Complexes for the Direct Hydrogenation of CO2 to HCOOH: A Direction for Atom‐Economic Approach

“…Polypyridines, especially tetra and quaterpyridine represent one of the most thoroughly studied classes of molecular catalysts towards CO 2 reduction to date . A variety of pristine and substituted quaterpyridine (qtpy) ligands have been synthesized over the past few decades ,. Co‐qtpy complexes are shown to be good electrocatalytic and photocatalytic reagent for the conversion of CO 2 to CO ,.…”
