Recently, organic semiconductors have been in limelight due to their high tunability, processibility and flexibility. In particular, organic one-dimensional(1D) nanostructures are proper for large scale integration. In order to fabricate highly efficient devices, their crystallinity is the critical point because it affects their intrinsic properties. Therefore, diverse methods have tried to control their properties such as crystallinity and morphology as well as growth direction. Herein, we introduced eutectic solidification to produce organic semiconducting 1D nanostructures. Fabricated structures had uniform size, unidirectionality and single crystallinity. In addition, halide ions were used to control their morphology. As a result, they appeared change in aspect ratio. To elucidate them, we investigated their morphologies, crystalline information and how those nanostructures become grown in view of molecular interaction with SEM, TEM, XRD and crystal visualization software. |
