Abstract

Abstract P-type Organic Semiconductors, TQx5-BT-DPP8 (1a) and TQx5-BT-DPP20 (1b), consisting of a donor unit of bithiophene (BT) and two acceptor units of thiadiazole quinoxaline (TQx) and diketopyrrolopyrrole (DPP), were synthesized, and their electronic states and physical properties were elucidated. These semiconductors demonstrate strong absorption extending from the visible to the near-infrared region, functioning effectively as strong donor dyes. The organic field-effect transistors (OFETs) exhibited normally on transistor characteristics, with carrier mobilities of 1.1 × 10−3 cm2/Vs for 1a and 3.3 × 10−4 cm2/Vs for 1b.
