Charge transport-driven self-assembly of conjugated polymers into 1D nanowires

Abstract

The crystallinity of conjugated polymers (CPs) imposed by nanoscale morphology is a significant controllable factor to regulate the charge transport in thin-film electronic devices. To enhance the performance of such devices, the dopant is widely utilized to fabricate CPs thin film. Recently, the solution-processable CPs nanostructure has gained many attentions due to its easy fabrication and property transfer to as-cast films with well-defined morphology without additional annealing process. However, the nanostructure formation/transformation by adding the dopant, which largely affects the morphology in whole films, has been rarely reported. In this line, we studied doping induced assembly of CPs into nanostructures without an additional process of introducing physical driving force and formation of interpenetrated 2D network structure by using TEM. This research can provide a basic knowledge of how to increase the charge mobility in a thin film where CPs nanostructure was controlled.
