Gold nanowires are obtained by photoreduction of linear self‐assemblies formed from Au(OH) 4 − and tetra‐alkyl ammonium ions at the water–chloroform interface. They are dissipative nanostructures formed only under non‐equilibrium conditions, which require continuous vectorial transport of ammonium ions across the interface. Nanocavities are observed in nanowires at almost regular intervals, which is a salient feature of dissipative structures.
