Peptide-based conducting nanomaterials are promising candidates for bioelectronics. Despite the remarkable advancements in the field of organic field effect transistors (OFETs), peptide-based OFETs with high mobility are scarce. We, herein, report phenylalanine-based core-modified self-assembling peptidic polymers showing p-type FET operation predominantly, with an on–off ratio of over 3 orders of magnitude. The peptide-based OFETs exhibited linear characteristics in a bottom-gate/bottom-contact configuration and showed a hole mobility of up to 9.29 cm² V⁻¹ s⁻¹ at room temperature, which is an exceptionally high field-effect performance for peptidic polymers. The OFETs also showed excellent long term storage stability and repeatability at room temperature under ambient conditions. The strategy presented here opens up avenues for designing a variety of peptidic polymers with OFET characteristics for applications in modern hybrid electronics.

基于自组装核修饰肽聚合物的有机场效应晶体管

基于肽的导电纳米材料是生物电子学的有希望的候选者。尽管在有机场效应晶体管（OFET）领域取得了显着进步，但仍缺乏具有高迁移率的基于肽的OFET。在此，我们报道了苯丙氨酸基核修饰的自组装肽聚合物，主要显示p型FET操作，开/关比超过3个数量级。基于肽的OFET在底栅/底接触构型中表现出线性特征，并显示出高达9.29 cm ² V ^-1 s ^-1的空穴迁移率在室温下，这对肽类聚合物具有极高的场效应性能。OFETs还显示出优异的长期储存稳定性和室温下在环境条件下的可重复性。本文介绍的策略为设计各种具有OFET特性的肽类聚合物开辟了途径，可用于现代混合电子学。
