Abstract

Regioregular poly(3-hexylthiophene) (RR-P3HT) nanotubes (200 nm in diameter) with tunable aspect ratios from 25 to 300 were prepared using a polymer melt wetting technique. Aspect-ratio tunability was achieved by controlling the wetting behavior of RR-P3HT melts in a template. The crystallinity and chain orientation of RR-P3HT were studied by grazing incidence X-ray diffraction, wide-angle X-ray diffraction, and polarized photoluminescence spectroscopy. Results suggest that RR-P3HT chains in the lamellar structure prefer to be perpendicular to the axis of the RR-P3HT nanotubes, forming a face-on conformation in the RR-P3HT nanotubes that leads to increased carrier mobility of RR-P3HT. Field-effect transistors were fabricated based on a single RR-P3HT nanotube and showed a carrier mobility of 0.14 ± 0.02 cm²/V·s.
