Merck, 445703-1G, Poly(3-hexylthiophene-2,5-diyl)

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 p- p stacking of the conjugated backbones. On account of the alkyl side group, P3HT is rendered hydrophobic in neutral state. Solution-to-solid phase transformation and thin film formation of poly(3-hexylthiophene) (P3HT) was reported in a study.
