Facile one-step growth and patterning of aligned squaraine nanowires via evaporation-induced self-assembly

Single-crystal squaraine dye nanowires are prepared on solid substrates by solvent evaporation. The nanowires can self-assemble into aligned arrays and patterns on substrates in parallel stripes. This simple one-step method for growth and patterning of aligned organic nanostructures would facilitate easy and low-cost fabrication of organic devices with one-dimensional nanostructures, especially for the fabrication of parallel arrays of devices.
