General description

LUMO level 3.1 eV

Poly(3-hexylthiophene) (P3HT) is a regioregular semiconducting polymer. It is used in organic electronics primarily because of its regular end-to-end arrangement of side chain, which allows efficient Π-Π stacking of the conjugated backbones. On account of the alkyl side group, P3HT is rendered hydrophobic in neutral state.
