Hydrogen bonds are noncovalent interactions able to improve the electronic properties of self-assembled semiconductors. Nevertheless, it is necessary to control the parameters influencing the formation of hydrogen bonds to achieve hierarchical structures with enhanced properties. In this work, we explore two hydrogen-bonded thiophene-capped diketopyrrolopyrrole (DPP) derivatives containing amides with different topology (C- or N-centered) and compare them to a control analogue without hydrogen bonds. We demonstrate the differences in the optoelectronic and self-assembly properties of the two amide-containing DPP derivatives, as well as in their charge carrier lifetimes. We prove the superior properties of the hydrogen-bonded derivatives in comparison to the control molecule without hydrogen bonds, and show that our molecular design strategy results in supramolecular structures with particularly long charge carrier lifetimes compared to other amide-containing semiconductors reported in the literature.

具有长载流子寿命的氢键有机半导体

氢键是非共价相互作用，能够改善自组装半导体的电子特性。然而，有必要控制影响氢键形成的参数以实现具有增强性能的分层结构。在这项工作中，我们探索了两种氢键噻吩封端的二酮吡咯并吡咯 (DPP) 衍生物，它们含有具有不同拓扑结构（C 或 N 中心）的酰胺，并将它们与没有氢键的对照类似物进行比较。我们展示了两种含酰胺的 DPP 衍生物的光电和自组装特性以及它们的电荷载流子寿命的差异。与没有氢键的控制分子相比，我们证明了氢键衍生物的优越性能，
