title = "Organoboron-Functionalization Enables the Hierarchical Assembly of Giant Polyoxometalate Nanocapsules",
abstract = "The aggregation of molecular metal oxides into larger superstructures can bridge the gap between molecular compounds and solid-state materials. Here, we report that functionalization of polyoxotungstates with organo-boron substituents leads to giant polyoxometalate-based nanocapsules with dimensions of up to 4 nm. A “lock and key” mechanism enables the site-specific anchoring of aromatic organo-boronic acids to metal-functionalized Dawson anions [M3P2W15O62]9− (M=TaV or NbV), resulting in unique nanocapsules containing up to twelve POM units. Experimental and theoretical studies provide initial insights into the role of the organo-boron moieties and the metal-functionalized POMs for the assembly of the giant aggregates. The study therefore lays the foundations for the design of organo-POM-based functional nanostructures.",
