The self‐assembly of short peptide offers versatile processes for adjusting the ordered stacking of organic functional materials to enhance photoinduced electron transfer. Herein, this study presents the first demonstration of the use of Aβ_16–22 peptide to prepare polythiophene/Aβ_16–22 assemblies for a photocatalytic water splitting system. Isothermal titration microcalorimetry results show that the driving forces for polythiophene/Aβ_16–22 assembly formation are electrostatic interactions, as well as hydrogen bonds and hydrophobic interactions. The assemblies accelerate the photoinduced electrons transfer from polythiophene upon light excitation and eventually enhance the hydrogen evolution. This work opens a new way into the development of biohybrid materials as novel photocatalytic water splitting platform for hydrogen evolution.

聚噻吩-肽生物杂交体增强光诱导氢的逸出

短肽的自组装为调节有机功能材料的有序堆积提供了通用的过程，以增强光诱导的电子转移。本文中，本研究首次证明了使用_Aβ16-22肽制备用于光催化水分解系统的聚噻吩/ _Aβ16-22组装体。等温滴定微量热法的结果表明，聚噻吩/ _Aβ16-22的驱动力组装形成是静电相互作用，以及氢键和疏水相互作用。组件在光激发时加速了光诱导电子从聚噻吩的转移，并最终增强了氢的释放。这项工作为生物混合材料的开发开辟了一条新途径，它是用于析氢的新型光催化水分解平台。
