A strategic side-chain engineering approach leads to the two orders of magnitude enhancement of charge carrier mobility in phenanthrene based fused aromatic thienopyrazine polymers. Hole carrier mobility up to 0.012 cm2/Vs can be obtained in thin film transistor devices. Polymers were also utilized to fabricate bulk heterojunction photovoltaic devices and the maximum PCE obtained in these OPV's was 1.15%. Most importantly, performances of the devices were correlated with thin morphological analysis performed by atomic force microscopy and grazing incidence X-ray scattering.

噻吩吡嗪聚合物中的载流子迁移率提升了两个数量级。在薄膜晶体管器件中,空穴载流子迁移率可达0.012 cm²/Vs。这些聚合物还被用于制备体异质结光伏器件,其中在这些有机光伏电池中获得的最大光电转换效率为1.15%。最重要的是,器件的性能与通过原子力显微镜和掠入射X射线散射进行的薄膜形态分析相关联。
