摘要

肽基非共价玻璃具有天然来源、绿色合成条件和自愈特性,代表了传统玻璃的一个有前途的可持续替代品。然而,开发具有高圆偏振发光(CPL)的手性非共价肽玻璃仍然是一项具有挑战性的任务。本文报道了一种在环境条件下由肌肽(Car)对映体和金属离子(Zn2+, Eu3+, Tb3+, Gd3+)构建对映体非共价肽玻璃的超分子配位协同诱导策略。所制得的手性Car(M)肽玻璃不仅具有高光学透明度(>90%)、大尺寸、易于加工的形状和高环境自愈性能,而且具有可编程的多色发射、手性放大和全光谱CPL编码。由于协同金属配位和氢键超分子相互作用,获得的手性Car(M)玻璃显示出创纪录的高CPL和可调CPL,不对称因子(|glum|)高达0.29。利用Car(M)玻璃的高透明度和多色手性发射,展示了一个防伪平台,包括灵活的多色QR码、滤波器解析模式、极化敏感莫尔斯电码和可编程点阵列加密。这项工作制造了新的手性非共价肽玻璃,具有快速自愈能力和高可调CPL性能,从而开拓了手性光子应用的新途径。

Chiral Noncovalent Peptide Glasses for Highly Circularly Polarized Luminescence.
Peptide-based noncovalent glasses exhibit natural origins, green synthesis conditions, and self-healing properties, representing a promising sustainable alternative to conventional glasses. However, developing chiral noncovalent peptide glasses with highly circularly polarized luminescence (CPL) is still a challenging task. Herein, a supramolecular-coordination synergistic induced strategy is reported for constructing enantiomeric noncovalent peptide glasses from carnosine (Car) enantiomers and metal ions (Zn2+, Eu3+, Tb3+, Gd3+) under ambient conditions. The resulting chiral Car(M) peptide glasses not only exhibit high optical transparency (>90%), large sizes, easily processable shapes, and high ambient self-healing performances, but also show programmable multicolor emission, chiral amplification, and full-spectrum CPL encoding. Due to the synergistic metal coordination and hydrogen-bonded supramolecular interactions, the obtained chiral Car(M) glasses reveal record-high and tunable CPL with dissymmetry factors (|glum|) up to 0.29. Leveraging the high transparency and multicolor chiral emission of Car(M) glasses, an anti-counterfeiting platform is demonstrated including flexible multicolor QR codes, filter-resolved patterns, polarization-sensitive Morse codes, and programmable dot-array encryption. This work fabricates new chiral noncovalent peptide glasses that exhibit rapid self-healing capabilities and high, tunable CPL performance, thereby pioneering a novel avenue for chiral photonic applications.
