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.

包含二酮吡咯并噻二唑-喹喔啉受体的 p 型有机半导体的合成、表征和 OFET 特性

合成了 P 型有机半导体 TQx5-BT-DPP8 (1a) 和 TQx5-BT-DPP20 (1b)，它们由一个供体单元噻吩（BT）和两个受体单元噻二唑喹喔啉（TQx）和二酮吡咯（DPP）组成，并阐明了它们的电子状态和物理性质。这些半导体显示出从可见光到近红外区域的强烈吸收，可有效地用作强供体染料。有机场效应晶体管（OFET）显示出正常的晶体管特性，1a 和 1b 的载流子迁移率分别为 1.1×10-3 cm2/Vs和 3.3×10-4 cm2/Vs。
