“…The combination of POM clusters and polymers has facilitated the realization of a series of POM–polymer hybrids. These may be prepared in a number of different ways to produce materials that are covalently bound or are the result of physical mixing . POM–polymer hybrids exhibit the functions of the precursor POM clusters and also have the high processability of polymers.…”

Organic polymers and inorganic clusters belong to two different disciplines and have completely different properties and structures. When a cluster is attached to the backbone of a polymer as a pendant, the resultant hybrid polymers (polyclusters) exhibit unique behaviours totally different from those of conventional polymers owing to the nanoscale size of the cluster and its particular interactions. Herein, the aggregation of a poly(polyoxometalate)—a polynorbornene backbone with inorganic polyoxometalate cluster pendants—upon addition of a non‐solvent to its dilute solution is reported. A three‐dimensional network of tangled and snake‐like nanothreads was observed. Direct visualisation of individual nanoscale clusters enabled identification of single chains within the nanothreads. These observations suggest that during the process of aggregation, the hybrid polymer forms curved or extended chains as a consequence of an armouring effect in which the collapsed cluster pendants wrap around the backbone. The collapse occurs because they become less soluble in the solvent/non‐solvent mixture. The extended chains then become entwined and form nanoropes consisting of multiple chains wound around each other. This study provides a deeper understanding of the nature of polyclusters and should also prove useful for their future development and application.

“…Due to the strong stabilities of covalent linkages compared to electrostatic interactions, studies have endeavoured to functionalise the POM cage through building covalent bonds to organic groups, [12][13][14] to achieve well-organised nanostructures. Interesting self-assembled amphiphilic structures have been detected, such as vesicles, [15][16][17] cylindrical micelles 16 or emulsions. 18 In our previous work, we attached double hydrocarbon chains onto a Dawson-type polyoxometalate, [P 2 W 17 O 61 ] 10ions (P 2 W 17 ), producing P 2 W 17 -2C n surfactants, with P 2 W 17 as the headgroup and 2C n standing for the double hydrocarbon chains of length n = 12, 14, 16 or 18.…”

Generally, polymers [18,19] , organic molecules [20] , and other organic/inorganic clusters [21,22] can be grafted on the POMs to fabricate the building blocks with different compositions and shapes by organic synthesis strategy.…”

Covalently modified polyoxometalates (POMs), which benefit from the synergistic effect between POMs and covalently grafted moieties, have received increasing attention in various fields. Recent studies on the covalently modified POMs mainly focus on the function-directed POMs assemblies. In this review, we summarized the latest progress (2017-2022) of covalently modified POMs from functional perspective, which can be classified as assembly chemistry, photochemistry, electrochemistry, homogeneous/heterogeneous catalysis and biological application.The roles of POMs and covalently grafted moieties in these hybrids, especially the rational design for the specific application were considered and emphasized.
