Polyoxometalates (POMs), a kind of molecular metal oxide cluster with unique physical‐chemical properties, have made essential contributions to creating efficient and robust electrocatalysts in renewable energy systems. Due to the fundamental advantages of POMs, such as the diversity of molecular structures and large numbers of redox active sites, numerous efforts have been devoted to extending their application areas. Up to now, various strategies of assembling POM molecules into superstructures, supporting POMs on heterogeneous substrates, and POMs‐derived metal compounds have been developed for synthesizing electrocatalysts. From a multidisciplinary perspective, we systematically summarize the latest advances in creating POM‐structured materials with a unique focus on their molecular fundamentals, electrocatalytic roles, and the recent breakthroughs of POMs and POM‐derived electrocatalysts. Notably, we focus on exposing the current states, essences, and mechanisms of how POM‐structured materials influence their electrocatalytic activities and disclose the critical requirements for future developments. The future challenges, objectives, comparisons, and perspectives for creating POM‐structured materials have also been systematically discussed. We anticipate that this review will offer a substantial impact on stimulating interdisciplinary efforts for the prosperities and widespread utilizations of POM‐structured materials in electrocatalysis.This article is protected by copyright.

“…POMtronics is a term coined in 2020 [41] that broadly refers to advanced applications of POMs deriving from their magnetic, electronic, and optical properties [123]. In a more narrow sense, POMtronics refers to POM-based nanoelectronics and spintronic devices [124]. A typical example may be a symmetrical and spherical POM sandwiched between two gold electrodes functioning as a current switch (Figure 18) [124].…”

Lacunary polyoxometalates (POMs) are negatively charged metal–oxo clusters, formally obtained from plenary topologies via fragment removal. Owing to the fragment removal, the lacunary POMs archetypes are rich in nucleophilic terminal oxo ligands, making them suitable for post-synthetic coordination with various heterometals. Trilacunary heteropolytungstates (hetero-POTs) based on bowl-shaped {W9O30} framework incorporating a central lone-pair containing {XO3} hetergroup (X = AsIII, SbIII, and BiIII) function as all-inorganic scaffolds that in the presence of d-block metal cations typically construct sandwich-like dimers of Hervé and/or Krebs. Herein we review the preparative approaches, as well as compositional and magnetic versatility of the constructed Hervé- and Krebs-type dimers and discuss prospective uses as POMtronics.

Polyoxoplatinates as covalently dynamic electron sponges and molecular electronics materials

Abstract: In organic systems, dynamic covalent chemistry provides an adaptive approach (i.e., “covalent dynamics”) where thermodynamic equilibriums are used to tailor structural and electronic changes in molecular assemblies. The covalent dynamics...
