Abstract Polyoxovanadates (POVs) have aroused increasing attentions in recent years because of their excellent catalytic properties and unique biochemical activities. The rational design and materialization of POVs towards practical applications remain a challenge. One main strategy for the preparation of polyoxometalate-based materials is to incorporate the inorganic metaloxo clusters into organic polymers. However, there is rare report about POV-based polymer mainly because that the vanadium with high valence state in clusters have negative impact on the design and synthesis. In this communication, we provided a new scheme to prepare POV-based polymers by stepwise functionalization and free radical polymerization for the first time. The influence from different organic ligands to the polymerization was also discussed. The results indicate that the free radical polymerization in the POV-based inorganic–organic system has the same tendency as the pure organic system, providing a new vision for the rational design of advanced POV-based polymer materials. Graphic Abstract For the first time, polyoxovanadate clusters were successfully linked to organic polymers by free radical polymerization reaction, providing a new vision for the rational design of advanced polyoxovanadate-based hybrid materials.

Introduction Polyoxovanadates (POVs) are a kind of inorganic vanadium-oxo nanoclusters with various architectures, fascinating catalytic properties, and unique bioactivities [1]. In order to adjust and excavate the inherent properties of POVs, organic modification has been considered as a significant method [2]. Benefiting from synergetic effect between POV clusters and organic ligands, the inorganic– organic hybrid materials deliver excellent properties in heterogeneous catalysis [3], photocatalysis [4], electrocatalysis [5], and biochemistry [6]. Interestingly, Liu and co-authors reported that POV-based networks exhibited outstanding performance in catalytic decontamination of odorants and toxic molecules, indicating that wrapping POVs into a network system is a promising idea for the improved application of such cluster [7, 8]. Actually, incorporating polyoxometalate clusters into organic polymers is an important route to realize the advanced functionalization of polyoxometalates with the traits of polymers (such as high molecular weight, high mechanical
