The morphology of conjugated polymers (CPs) is a significant parameter to decide charge transfer property and having one-dimensional nanostructure, especially, is highly suitable for charge transfer. In this line, pre-assembly of conjugated polymers into nanowires (NWs) in the solution state has been used with advantages of well-controlled morphology, availability of large scale production and cost reduction. However, this solution process inevitably introduces an additional physical driving force for assembly of the CPs. Therefore, we have introduced the doping method to proceed nanowire growth. This process can perform nanowire growth and dope simultaneously without introducing a physical driving force. We demonstrate the assembly of P3HT into NWs by addition of dopant in a single good solvent, and the NWs growth mechanism is studied. This research provides a useful strategy for fabricating doped organic semiconducting NWs with high electrical performance. |
