Recent advances in high-mobility polymeric semiconductor materials

Abstract

Significant progress has been made in polymeric semiconductors and their organic field-effect transistors (OFETs) since 1980s. To date, hundreds of polymeric semiconductors have been reported and used for OFETs. The hole mobility above 36.3 cm2·V-1·s-1 has been achieved, which can be competitive with organic small semiconductors and even amorphous silicon. In this review, the recent progress in high-mobility polymeric semiconductor materials has been summarized from the perspective of design, synthesis, and OFET devices performance. Moreover, the recent developments are systematically summarized and analyzed according to different types of polymeric semiconductors, including p-type, n-type, and ambipolar polymeric semiconductors. The analysis about the relationship among the molecular structure-aggregation structure-OFET devices performance may guide the rational molecule design in the polymeric semiconductor materials with excellently comprehensive performance in the future.
