Hierarchical Assembly of {Fe_(13)} Oxygen-Bridged Clusters into a Close-Packed Superstructure

摘要

Hierarchical materials can be regarded as systems in which small units are incorporated into larger superstructures,thereby investing the resulting construct with a hierarchy of properties that operate on different scales.Such systems become of particular interest when nanometer scales are involved,as these represent a situation in which nanoparticles are organized into a specific array.The organization of nanoparticles is important in terms of creating devices but poses significant difficulties if the particles have to be physically arranged,for example,by using electron-beam lithography.Therefore,the idea of the combination of such particles along chemical principles is attractive as it leaves the chemical-bonding interactions to do the work.
