Functional Polymers: High-Mobility Conjugated Polymers Based on Fused-Thiophene Building Blocks
Yao Liu, Yunqi Liu,* Xiaowei Zhan*
Organic field-effect transistors (OFETs) are a promising cost-effective alternative to siliconbased field-effect transistors, and possess low-cost, light-weight, and flexibility advantages.
Conjugated polymers based on fused-thiophene building blocks have received considerable attention in the emerging field of organic electronics. In this review the most recent developments in conjugated polymers based on fused-thiophene rings for high-performance OFETs are summarized. The focus is on correlations of polymer chemical structures with properties, such as energy levels, filmforming property, film morphology, and OFET performance. This structure-property relationship analysis may guide rational structural design and evaluation of organic semiconductors. This article is additionally featured on MaterialsViews.
