Abstract: One dimensional organic nanostructures were prepared via solvent exchange method and characterized by SEM,TEM and ED.The growth process of the nanowires was also analyzed and discussed.Their spectral properties were researched by UV-vis absorption and fluorescence spectrometers.The results showed that optical properties of molecular aggregates were strongly dependent on the morphology and size of the organic nanostructures.They performed distinct optical properties different from their solution and bulk materials.

Key words: nanomaterials, one-dimensional organic nanomaterials, solvent exchange method
