摘要：

Solid-state spectra for 98% HT-HT bonding configuration regioregular polyhexylthiophene (PHT) show it possesses the longest conjugation length, approximately 28 monomer units, of any PHT. Similar measurements for 1:1:1:1 configuration regiorandom PHT indicate shorter average conjugation lengths explainable by structural considerations. Regioregular PHT solvatochromism is consistent with that previously reported for other PHT's while the regiorandom form exhibits no significant solvent sensitivity. Average conjugation lengths are estimated for the two solvated forms.
