Combination of top-down and bottom-up approaches with small organogelators produced dual-patterned honeycomb lines in nanometer scale. The breath figure technique was applied to a photoresponsive small molecule to self-assemble into a hierarchically ordered honeycomb structure followed by the spontaneous formation of supramolecular fibrillar networks. The structure was again patterned by exposure to UV through a photomask, which induced selective chemical crosslinking in the exposed region. After developing, honeycomb lines were obtained in a pre-defined way. This process is very promising in fabrication of “custom” honeycomb patterns, because it is simple, applicable to various substrates, and doesn’t need additional photoresists and processes. |
