Polyoxometalate – rich thin films with controlled structure and function for designer electronics

During the last two decades, polyoxometalates (POMs) have attracted growing attention due to their potential application as functional materials potentially enabling new device design and opening new areas of technology. POMs are metal-oxide clusters of early transition metals Mo, W, V, etc with a diverse range of structures and properties, such as reversible electrical capacitance,[1] programmable surface 0D, 2D or 3D structure[2] which could together be of potential application in ultra-high-density data storage,[3],5 catalysis[4] and also in medicine as antiviral drugs.[5] In the present work, we show that it is possible to assemble structured thin-films by the self-assembly/organization…
