Scanning tunneling microscopy images of thin films of polythiophene cast on highly oriented pyrolytic graphite gives structural insight on both local (chain-packing and conformational) and mesoscopic (polycrystal structure) scales. It is revealed that 2D polycrystals form mono-domains (20 nm parallel and perpendicular to the polymer backbone) (see Figure), partially interconnected by folded chains.
