摘要

在近红外（NIR）区域表现出强吸收的有机半导体作为新的有机光电材料越来越受到关注。本文报道了一种基于长共轭长度双（噻吩二酮吡咯并吡咯）（2DPP-Q-CN）的新型醌类分子的合成、吸收和半导体性质。结果表明，这种新的醌类分子在近红外区表现出较强的吸收，摩尔消光系数为380 000米-1厘米-1。此外，2DPP-Q-CN薄膜表现出平衡的双极半导体性质，空穴和电子迁移率分别高达0.19和0.20 cm2 V−1 s−1。

An extended quinoid molecule based on bis(thiophene-diketopyrrolopyrrole) with balanced ambipolar semiconducting properties and strong near-infrared absorption†

Organic semiconductors that exhibit strong absorption in the near-infrared (NIR) region have received increasing attention as new organic optoelectronic materials. In this paper, we report the synthesis, absorption and semiconducting properties of a new quinoid molecule based on bis(thiophene-diketopyrrolopyrrole) (2DPP-Q-CN) with a long conjugation length. The results reveal that this new quinoid molecule shows strong absorption in the NIR region with a molar extinction coefficient of 380 000 M⁻¹ cm⁻¹. Moreover, the thin film of 2DPP-Q-CN exhibits balanced ambipolar semiconducting properties with hole and electron mobilities up to 0.19 and 0.20 cm² V⁻¹ s⁻¹, respectively.
