An electrochromic system based on a self‐assembled dipeptide‐appended redox‐active quinquethiophene π‐gel is reported. The designed peptide‐quinquethiophene consists of a symmetric bolaamphiphile that has two segments: a redox‐active π‐conjugated quinquethiophene core for electrochromism, and peptide motif for the involvement of molecular self‐assembly. Investigations reveal that self‐assembly and electrochromic properties of the π‐gel are strongly dependent on the relative orientation of peptidic and quinquethiophene scaffolds in the self‐assembly system. The colors of the π‐gel film are very stable with fast and controlled switching speed at room temperature.

氧化还原活性肽功能化的喹噻吩基电致变色π凝胶

报道了基于自组装的二肽附加的氧化还原活性喹啉噻吩π-凝胶的电致变色系统。设计的肽喹喹噻吩由对称的两亲性苯丙氨酸组成，该片段具有两个部分：用于电致变色的氧化还原活性π共轭喹硫噻吩核心和用于参与分子自组装的肽基序。研究表明，π-gel的自组装和电致变色特性在很大程度上取决于肽和quinquethiophene支架在自组装系统中的相对取向。π-gel薄膜的颜色非常稳定，在室温下具有快速且受控的切换速度。
