Stimuli-responsive Prussian blue analogues

Abstract

The metal--cyanide frameworks known as Prussian blue analogues display a suite of diverse and tuneable properties. In particular, they are often highly susceptible to modification by external stimuli, such as temperature, pressure, radiation, or adsorbed guests. This can lead to rare and intriguing phenomena---including humidity-induced magnetism, electrochromism, or light-switchable electronic bistability---which opens up for a wide range of potential applications. The present article briefly surveys the stimuli-responsive behaviour in Prussian blue analogues, thereby identifying areas with potential for future developments.
