The effects of soft lithography on P3HT nanolines

The study explores the impact of h-PDMS stamp-based nanopatterning techniques on the alignment and crystallite size of poly(3-hexylthiophene) (P3HT) molecules. Utilizing atomic force phase imaging, x-ray diffraction, and thin-film field-effect transistor measurements, it reveals that solvent evaporation rates influence crystallite growth, leading to an isotropic chain distribution. The research highlights the need for further investigation into silanized monolayers to determine if nano-confinement can induce crystallite orientation, which is crucial for enhancing optoelectronic device performance.
