聚(3-己基噻吩-2,5-二基)用途： 作为活性 半导体制备有机场发射晶体管(OFET, organic field emission transistor)。 绝缘碱性侧链和π-π链间堆积之间的相分离层(phase-segregatedlayer)构成了规整P3HT的微晶结构域。 带来高电荷迁移率，增强OFET性能。 作为前体合成P3HT-PCBM（[6,6]-苯基C61-丁酸甲酯）共混物薄膜。P3HT薄膜的高结晶度提高了有机光伏电池的效率。 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.
