Abstract
Orienting semiconducting polymers (SCPs) using solution-processable techniques for organic electronic devices is essential for realizing a printable electronics device. Preparation of oriented films on liquid substrates and transferring on actual device substrate offers many advantages, including layer-by-layer coating, independent control of morphology, freedom to choose substrates, and device geometry. The floating films transfer method (FTM) has emerged as a unique method to prepare oriented films of SCP using solution processing. Here, we review recent progress in this method from the viewpoint of improvement in FTM to orient SCPs and their anisotropy in organic field effect transistors. In addition, the use of FTM films in sensing applications is also reviewed.
