Noncovalent supramolecular assembly of hexagonally ordered mesoscale Prussian blue analogue

A new mesostructured Prussian blue analogue was obtained through a noncovalent templating by cetylpyridinium bromide in formamide in the presence of Co2+ linking ions. This phase possesses a hexagonally ordered mesostructure with a framework based on the [Fe(CN)6]3− anions linked by Co2+ ions which was noncovalently templated with cetylpyridinium cations.
