Self-assembly of triangular polyoxometalate–organic hybrid macroions in mixed solvents†
Abstract
Triangular-shaped inorganic–organic hybrids with three polyoxometalate (POM) clusters as polar head groups are found to self-assemble into blackberry structures in water–acetone solvent mixtures containing 65–95 vol% acetone. The driving force for the self-assembly of the hybrids is shown to originate from the electrostatic counterion-cluster interactions.
