Organic one-dimensional (1D) nanostructures represent attractive building blocks for nano-scale optoelectronic devices because they behave in a unique way that differentiates them from the isolated molecule or the bulk. The synthesis of such organic nanostructures with good control of both size and morphology is still a challenge due to the weak intermolecular interactions in organic molecules compared with those in inorganic materials. Anodic aluminum oxide (AAO) membranes are excellent templates for fabricating organic 1D nanostructures with high arrangement regularity, variable length and diameter. The highly ordered nano-sized channels of the AAO templates force the organic molecules to assemble within a well-defined space. Moreover, the AAO templates are thermal and mechanical stable as well as resistant to organic solvents. By using a combination of solvent saturation and low temperature solvent annealing process, crystalline organic semiconductor nanowires were fabricated with AAO as template. Besides the organic nanostructures, ordered 1D nanostructure arrays of other materials were also synthesized in our group, including different semiconductors and metals.
