Ln-Ag heterometallic coordination polymers

Abstract

<jats:title>Abstract</jats:title><jats:p>The last few years have seen an increasing interest in the study of lanthanide-silver (Ln-Ag) heterometallic coordination polymers due to their potential applications. It has led to intense activity of chemists to produce Ln-Ag heterometallic coordination polymers and investigate their properties. In this review, we summarize recent research development in the fascinating and challenging field of Ln-Ag heterometallic coordination polymers. This review covers 182 Ln-Ag heterometallic coordination polymers, which are categorized by the kind of ligand as N-heterocyclic carboxylate ligands and others. There are three categories of Ln-Ag coordination polymer based on N-heterocyclic carboxylate ligands: one dimensional (1D), 2D, and 3D. The 3D part was divided into Ln-Ag coordination polymers based on pyridine carboxylate ligands and other N-heterocyclic carboxylate ligands. This perspective illustrates the coordination features of compounds constructed by N-heterocyclic carboxylate ligands. Luminescent properties are also discussed.</jats:p>

Heterometallic coordination polymers as heterogeneous electrocatalysts

“…41 A short distance between the metal centres is also important for electronic communication between the catalytic centres in heterometallic CPs. [42][43][44] In some cases, additives such as metal clusters (redox centre), Nafion (ion-conductive material or binder), and activated carbon (electrically conductive material) are incorporated to endow heterometallic CPs with electrocatalytic activity. Currently, optimizing the electrode fabrication method makes it possible to investigate the redox behaviour of heterometallic CPs that are insoluble in any solvents without decomposition.…”

Dual emissive Ln(iii)–Ag(i) heterometallic chains based on tris(2-pyridyl)phosphine oxide

“…Notably, the f-d heterometallic complexes that demonstrate emission involving both metal centers are very rare, and most of them exhibit only lanthanide-centered emission. 41 For example, 3D coordination polymers [Ln 2 Ag 2 (sba) 2 (ina) 4 (H 2 O) 2 ] n (Ln = Sm, Dy; Hina -isonicotinic acid; H 2 sba -2-sulfobenzoicacid) are rare examples of 4f-4d heterometallic coordination compounds exhibiting both d 10 -metal-based and 4f-metal-centered emissions. 42 CPs 1-4 show pronounced excitation wavelength dependent photoluminescence.…”

Near-Infrared Emitters: Stepwise Assembly of Two Heteropolynuclear Clusters with Tunable AgI:ZnII Ratio

“…Therefore, stable and tunable NIR materials are urgently needed, and the d 6 , d 8 , and d 10 metal coordination compounds with extraordinary photophysical properties recently appear to be promising substitutes for those luminophores . However, reports of Ag­(I) coordination compounds with NIR emission characteristics remain relatively rare until now, and most of the examples are Ag–Ln heterometallic compounds …”
