Self-assembled structures with circularly polarized luminescence (CPL) have attracted great attention in recent years. π-conjugated N-terminal amino acids with chiral amino acid residues and luminophores are capable of forming self-assembled structures at hierarchical levels, whereby chirality can be transferred to the macroscopic scale with easily modulated CPL properties. Due to the presence of multiple noncovalent binding sites, including hydrogen bonding and aromatic interactions, π-conjugated N-terminal amino acids are emerging core candidates for incorporation into multicomponent self-assembled architectures, accomplishing rational control over supramolecular chirality as well as showing rich chiroptical properties. In this Minireview, we provide a brief summary of multiple-component coassembled systems comprising π-conjugated N-terminal amino acids, small organic species and metal ions. The synthesis of helical structures and manipulation of supramolecular chirality by controlling the self-assembled species is introduced, and the CPL properties of multiple-component π-conjugated N-terminal amino acids are also briefly summarized.
近年来，具有圆偏振发光（CPL）的自组装结构引起了极大的关注。具有手性氨基酸残基和发光团的π-共轭 N-端氨基酸能够在层次结构上形成自组装结构，从而可以将手性转移到具有可调节 CPL 性质的宏观尺度上。由于存在多个非共价结合位点，包括氢键和芳香相互作用，π-共轭 N-端氨基酸是作为多组分自组装结构的核心候选物出现的，能够实现对超分子手性的合理控制，并表现出丰富的手性光学性质。在这篇综述中，我们简要总结了包含π-共轭 N-端氨基酸、小分子和金属离子的多组分共组装体系。介绍了通过控制自组装体来合成螺旋结构和操纵超分子手性的方法，并简要总结了多组分π-共轭 N-端氨基酸的 CPL 性质。
