Supramolecular control over the morphology of bio-inspired poly(3-hexylthiophene) for organic thin film transistors

An adenine-functionalized poly(3-hexylthiophene) (PAT) was treated with adenosine triphosphate (ATP) to obtain selectively self-patterned layers. Interchain charge transport resulting from side chain-induced self-organization was selected to control the polymer morphology totally without the need of additional chemical synthetic processing.330
