Here, novel colloidal materials were prepared for the first time from the organo-functionalized Anderson structure polyoxometalate species [NaV^IV₆O₆{(OCH₂CH₂)₂N(CH₂CH₂OH)}₆]Cl·H₂O and the mixed-addenda Keggin structure polyoxometalate, K₄(PVW₁₁O₄₀). The materials were characterized by SEM, TGA, FTIR and UV-vis spectroscopy. The colloidal materials are readily separated from suspension in the form of redistributable micrometer-scale monoliths, which may be considered a type of POM heterogenation. The monoliths are insoluble in low polarity media and lower aliphatic alcohols and readily form thin-films (δ < 100 um) by solvent casting.
