Hybrid Organic–Inorganic Polyoxometalates: Functionalization of VIV/ VV Nanosized Clusters to Produce Molecular Capsules

Functionalization of polyoxovanadate clusters using phosphonate and arsonate ligands results in molecular capsules (see structure; green V, purple P, red O, black C). Through the use of extended homologous ligands, these hybrid organic-inorganic capsules can be successively elongated into tubular molecules.
