Abstract:
Keeping their cool: Fabrication of a 2D weblike nanonetwork of gold was successfully demonstrated through a two-step procedure including complexation of gold precursors to a weblike supramolecular assembly of surfactant followed by in situ reduction of the precursors to gold. Molecular assemblies stabilized by hydrogen bonding provided a sound template, leading to the highly integrated structure of gold through room-temperature (cold) nanostructure fusion.
