Enhanced Hole Mobility in Regioregular Polythiophene Infiltrated in Straight Nanopores

Abstract
We demonstrate that the hole mobility in regioregular poly(3‐hexylthiophene) can be enhanced by a factor of 20 by infiltrating it into straight nanopores of anodic alumina. Optical characterization shows that the polymer chains are partially aligned in the charge‐transport direction.
