How to sense and recognize achiral organic molecules using chiroptical responses are rather challenging and have not been well addressed so far. In this work, N-terminal aromatic amino acids were conjugated to the surface of nanoclay noncovalently, providing chiral environments to trap guest molecules. It allowed for the selective chiral recognition of achiral dyes using diversified chiroptical responses. Halogen bonding played key role in the emergence of chiral molecular arrangements with synergistic coassembly effect.

纳米粘土组件中非手性物质的选择性手性识别

如何使用按摩疗法的反应来感测和识别非手性有机分子是一项颇具挑战性的工作，到目前为止尚未得到很好的解决。在这项工作中，N末端芳香族氨基酸非共价结合到纳米粘土的表面上，从而提供了一种手性环境来捕获客体分子。它允许使用多样化的手性响应选择性地手性识别手性染料。卤素键在具有协同共组装作用的手性分子排列的出现中起关键作用。
