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。

The present invention relates to a strong base-initiated N-carboxyanhydride rapid ring-opening polymerisation method. Specifically, the method comprises steps of: performing a polymerisation reaction with one or more amino acid N-carboxyanhydride monomers in an organic solvent in the presence of an initiator, so as to form an amino acid polymer, wherein the initiator is selected from the following group: LiHMDS, NaHMDS, KHMDS, or a combination thereof. The method significantly increases the speed of traditional NCA polymerisation and prepares a long-chain polymer, and the prepared amino acid polymer may be used as an anti-bacterial material, an anti-tumour material, a tissue engineering scaffold or a self-assembling material.
