摘要

Polymer-based organic thin-film transistors (OTFTs) and organic photovoltaics (OPVs) have attracted much interest in recent years due to their solution processability and mechanical flexibility, which potentially allow them to be manufactured using low-cost, high-throughput processes such as roll-to-roll printing and inkjet printing. In recent years, the development of novel materials for these applications has contributed to significant improvements in device performance. In the field of OTFTs, the development of polythiophene derivatives such as poly(3,3-dialkyl-quaterthiophene) (PQT) and poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT) has resulted in OTFTs with hole mobilities of between 0.2 and 0.6 cm~2V~(-1)s~(-1). The development of low bandgap polymer donors has meanwhile helped to lift solar cell power conversion efficiencies (PCEs) to above 6%. However, there have been few reports of polymers that perform well in both OTFTs and OPVs. The development of such versatile polymers could be beneficial for applications which incorporate both types of devices.
