We report a new synthetic strategy of combining N-carboxyanhydride (NCA) chemistry and photonic crystals for the fabrication of polypeptide structural color films. Driven by surface-initiated ring-opening polymerization, the di-NCA derivative of l-cystine (Cys) is introduced to replicate the functionalized colloidal crystal templates and construct freestanding P(Cys) films with tunable structural color. Furthermore, the feasibility of preparing patterned polypeptide photonic films is demonstrated via template microfabrication. Because of the incorporation of l-glutamate (Glu) components, the P(Cys-co-Glu) co-polypeptide films are endowed with a visual color responsiveness toward pH changes. Additionally, the polypeptide photonic films show on-demand degradability. Given the large family of amino acid building blocks, this powerful and versatile approach paves the way for chemical derivatization of multifunctional peptide-based optical platforms.

具有可调结构颜色的仿生多肽光子薄膜

我们报告了一种结合N-羧酸酐（NCA）化学和光子晶体来制造多肽结构彩色薄膜的新合成策略。在表面引发的开环聚合驱动下，引入L-胱氨酸（Cys）的二NCA衍生物来复制功能化胶体晶体模板并构建具有可调节结构颜色的独立P（Cys）薄膜。此外，通过模板微加工证明了制备图案化多肽光子薄膜的可行性。由于L-谷氨酸(Glu)成分的掺入，P(Cys- co -Glu)共聚肽膜赋予了对pH变化的视觉颜色响应性。此外，多肽光子薄膜表现出按需降解性。考虑到氨基酸构建模块的大家族，这种强大且多功能的方法为多功能肽基光学平台的化学衍生化铺平了道路。
