Supramolecular assembly at interfaces: Formation of an extended two-dimensional coordinate covalent square grid network at the air-water interface

A two-dimensional iron-nickel cyanide-bridged network at the air-water interface is formed due to the result of reaction of a Langmuir monolayer of an amphiphitic pentacyanoferrate complex with Ni2+ ions from the subphase. Characterization of these networks by different techniques was done, and it was found that air-water interface can function as a structure-directing element in the assembly of new supramolecular network solids and may help in the development of nanoscale materials.
