聚（3-己基噻吩）在甲苯中的吸收边表现出显着的红移后，应用高静水压力。一个带隙小至1.7 eV已被评估在此解决方案下的流体静压。这甚至比未取代的聚噻吩膜（2.0eV）小得多，并且通过由于相邻噻吩环之间的扭转角减小而增加的共面性来解释。
The absorption edge of poly(3-hexylthiophene) in toluene demonstrates a remarkable red shift upon application of high hydrostatic pressure. A band gap as small as 1.7 eV has been evaluated in this solution under hydrostatic pressure. This is much smaller even than that of a nonsubstituted polythiophene film (2.0 eV) and is explained by the increased co-planarity due to the decreased torsion angle between neighboring thiophene rings.
