Nanoarchitectonics: A new materials horizon for prussian blue and its analogues

Although porous materials based on coordination compounds, including metal-organic frameworks (MOFs) and porous coordination polymers (PCPs), have well-defined pore structures and promising properties, they can efficiently be prepared by conventional and facile methods. Among coordination compounds, Prussian blue (PB) and its analogues (PBA) show high physical/chemical properties and potential as a multifunctional platform for various applications such as information records, sensing, batteries, biomedicine, imaging, and water purification. This review introduces versatile paths for nano- and meso-structural controls and demonstrates strong relationship between nanoarchitectures and properties with regard to PB and PBAs. This review will provide some guidance for future derivations of nanoarchitectonics based on coordination compounds which are PB and PBA.
