Cuprite (Cu2O) nanowires with diameter of 25−100 nm were electrodeposited from anionicsurfactant sodium bis(2-ethylhexyl) sulfosuccinate reverse hexagonal liquid crystalline phase.The nanowires can be grown to up to tens of micrometers in length by simply changing theelectrodeposition time. Resistivity measurements suggest improved alignment of the reversehexagonal liquid crystalline phase under electric field during electrodeposition. The enhancedalignment of the liquid crystalline phase appears essential for the growth of nanowires withhigh aspect ratio. This new synthesis approach is fast and simple, and a great variety oforganized assemblies are potentially available by simply adjusting the liquid crystal typeand composition.
