Targeting ordered oligothiophene fibers with enhanced functional properties by interplay of self-assembly and wet lithography

Reproducible spatial control of a self-assembly process of fiber-forming oligothiophenes was achieved by using confinement effects. This strategy allowed the direct integration with a precise control over density, orientation, and size of supramolecular semiconducting fibers in OFET devices, demonstrating that well-aligned fibers exhibit a substantial enhancement of electrical performances.
