High-Performance Ambipolar Diketopyrrolopyrrole-Thieno[3,2-balthiophene Copolymer Field-Effect Transistors with Balanced Hole and Electron Mobilities

摘要

The performance of organic field-effect transistors (OFETs) based on solution-processed conjugated polymers has undergone remarkable progress recently as a result of combined efforts in material synthesis and processing/fabrication opti-mization, as well as understanding of charge transport and microstructure. Current, state-of-the-art conjugated polymers, optimized for either p-channel or n-channel OFET operation, achieve high field-effect mobilities on the order of 1 cm~2 V~(-1) s~(-1) for unipolar p-channel operation and close to 1 cm~2 V~(-1) s~(-1) for unipolar n-channel operation.
