| Uniform nanostructures of organic electronic materials have seen tremendous interest in the past decade. Many organic nanotubes have been made and fully characterized but there are very few examples of solid organic nanorods. We have developed a general method for synthesizing uniform organic nanorods of functionalized pyrene, perylene, anthracene and several other organic molecules. We used anodized alumina templates and low temperature solvent annealing to make nanorods with diameters adjustable between 35 to 200 nm diameter and 50 microns long. We characterized the morphology and growth process of the nanorods using Scanning Electron Microscopy, Tunneling Electron Microscopy, Atomic Force Microscopy and Fluorescence spectroscopy. The nanorods are crystalline and rigid with interesting photophysical characteristics such as wave guiding and energy transfer. Possible applications like metal ion sensing and light harvesting will be discussed. |
