Abstract
Single-crystalline nanowires and nanoparticles of 2,5,8,11-tetra-tert- butylperylene (TBPe) can be easily obtained by controlling the solvent composition (solubility) of TBPe in the mixed solution. Changes in shape observed are accompanied by distinct changes in optical properties. Crystal structure analysis shows that they have different molecular stacking modes, which were believed to be responsible for the properties difference. This also helps us gain insight into the crystal growth process and better understand the formation mechanism of different morphological crystals. We believe that the crystal structure may be locked at the nucleation stage and expected to vary with the solubility change. This also offers original explanations for the shape-dependent properties in organic nanocrystals. © 2011 American Chemical Society.
