基于聚（2，5-双（3-烷基噻吩-2-基）噻吩并[3，2-B]噻吩）的液晶半导体聚合物类最近在有机电子学领域引起了极大的兴趣，这主要是由于它们在场效应晶体管（FET）结构中具有有前途的性能，其器件迁移率达到（如果不是超过）非晶硅结构的器件迁移率。然而，对这些有趣的大分子的体电荷传输特性知之甚少。因此，我们对这类有机半导体的一种特定材料-即聚（2，5-双（3-十二烷基噻吩-2-基）噻吩并[3，2-B]噻吩）pBTTT-C12-进行了飞行时间（TOF）光电导测量，并试图将该聚合物的电子本体性质与其随温度的微观结构发展相关联。退火的效果也进行了研究。
The class of liquid-crystalline semiconducting polymers based on poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2-b]thiophene) recently has attracted significant interest in the field of organic electronics, predominantly due to their promising performance in field-effect transistor (FET) structures with device mobilities reaching—if not exceeding—those of amorphous silicon architectures. Less is known, however, about the bulk charge-transport properties of these interesting macromolecules. We therefore conducted time-of-flight (TOF) photoconductivity measurements on one particular material of this class of organic semiconductors—i.e. poly(2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene), pBTTT-C12—and attempted to correlate the electronic bulk properties of this polymer with its microstructural development with temperature. The effect of annealing was also investigated.
