Influence of surface and intermolecular interactions on the properties of supported polyoxometalates

Abstract

Polyoxometalates (POMs) with localized radical or open-shell metal sites have the potential to be used as transformative electronic spin based molecular qubits (MQs) for quantum computing (QC). For practical applications,...

Polyoxometalate nanocluster-infused triple IPN hydrogels for excellent microplastic removal from contaminated water: detection, photodegradation, and upcycling

“…POMs are utilized as photocatalysts due to several advantageous properties: their redox capability, adaptable stability, distinct active sites within their crystal structures, and tunable light absorption through the introduction of transition metals into the POMs. 8,33,61,62 However, to evaluate the photocatalytic properties, the band gap energy of Cu-POM was determined using the Tauc plot, as detailed in ESI, S2. † Fig.…”

“…6−9 The selfassembly of molecules on surfaces is governed by the specific interactions between molecules and the chemistry at their interface and POMs are no exception; their organization, orientation, stability, reactivity, and redox activity depend strongly on the properties of the substrate 10 (e.g., hydrophobic vs hydrophilic 11 ) and its passivation/functionalization. 12−14 It can also be influenced by methods of molecular deposition 6,15 and the adsorption of POM itself can exert electronic effects on, e.g., biomolecular nanostructures such as DNA origami confined to the surface. 16 The utility of POMs as redox-active building blocks includes the investigation of electron transport in the context of polarizability, 17 spintronics, 18,19 organic neuromorphics, 20−22 , thermoelectrics, 23 molecular magnetism, 24,25 molecular sensors, 26 and plasmonics.…”

“…Polyoxometalate (POM) compounds designed to form robust SAMs , offer a unique molecular platform for pursuing these goals. The relative ease of systematically augmenting POMs toward inorganic–organic hybrid structures of interest is beneficial for tailoring the POM reactivity on substrate surfaces via the ligand functionality and of the corresponding charge-transfer properties. − The self-assembly of molecules on surfaces is governed by the specific interactions between molecules and the chemistry at their interface and POMs are no exception; their organization, orientation, stability, reactivity, and redox activity depend strongly on the properties of the substrate (e.g., hydrophobic vs hydrophilic) and its passivation/functionalization. − It can also be influenced by methods of molecular deposition , and the adsorption of POM itself can exert electronic effects on, e.g., biomolecular nanostructures such as DNA origami confined to the surface .
