ABSTRACT
Many high-performance conjugated polymers for organic photovoltaics and transistors crystallize such that chains are parallel, resulting in significant anisotropy of the nanoscale charge transport properties. Here we demonstrate an unusual intercrystallite relationship where thin lamellae adopt a preferred epitaxial relationship with crossed-chains at the interface. The crossed-chains may allow either crystal to use the other as an "electronic shunt", creating efficient quasi-three-dimensional transport pathways that reduce the severity of grain boundaries and defects in limiting transport.
