Abstract

Simple yet versatile routes to generate macroscopically aligned 3-D NP arrays with tunable structures in supramolecular nanocomposite thin films are presented using faceted and lithographically patterned surfaces. These studies provide a powerful platform for the investigation of emerging structure-property relationships in functional nanocomposites, paving the way for the realization of next-generation devices.

Keywords: 3-D nanoparticle assembly; graphoepitaxy; long-range order; saw-toothed pattern; supramolecular nanocomposite; thin film.
