We show that polybis(thienyl)thienodia-thiazolethiophene (PDDTT), a high-performance semiconducting polymer for photodetectors and field-effect transistors, has strong performance dependence on annealing temperature. An unprecedented increase of 3 orders of magnitude is observed in both transistor and photoconductive properties. XRD and AFM evidence points to increased ordering in PDDTT films with annealing. This correlation highlights the importance that order has in determining performance in PDDTT and has possible implications in the design of polymers.

热处理后的 PDDTT 观察：性能与顺序之间的相关性

我们表明聚双（噻吩基）噻吩并噻唑噻吩 (PDDTT) 是一种用于光电探测器和场效应晶体管的高性能半导体聚合物，对退火温度具有很强的性能依赖性。在晶体管和光电导性能方面都观察到了前所未有的 3 个数量级的增加。XRD 和 AFM 证据表明，经过退火处理的 PDDTT 薄膜的有序性增加。这种相关性突出了顺序在决定 PDDTT 性能方面的重要性，并可能对聚合物的设计产生影响。
