Miniemulsion periphery polymerization (MEPP) has been used for the synthesis of Prussian blue (PB) nanocubes. Pentacyano ferrate functionalized surfactant in combination with a co‐surfactant containing 4‐(dimethylamino)‐pyridine (DMAP) or OH end groups in lieu of ferrate functionality (EPE‐DMAP or EPE‐OH) were used to prepare a miniemulsion system comprising 20 wt.‐% toluene and 0.5 wt.‐% total surfactant. On addition of Fe 3+ to the miniemulsion, metal coordination polymerization occurred with nanocubes generated when the ratio of EPE‐Fe:EPE‐DMAP (or EPE‐OH) was 60:40 (w/w). The resulting nanocubes are apparently amorphous. Particles with irregular shape have been observed on reacting EPE‐Fe and Fe 3+ directly in water, thus suggesting that confinement of the polymerization field on the periphery of the miniemulsion droplets is a primary factor in the formation of cubic structures.
