Amino acids, as the fundamental building blocks of proteins, are essential components of life. Different amino acids, with their unique structures, play vital roles in biological systems. Additionally, amino acids serve as important raw materials in the food and pharmaceutical industries, functional materials, and organic synthesis. The precise chemoselective recognition of the 20 common amino acids represents a highly significant research endeavor. Schiff base structures, characterized by the C=N double bond, possess unique properties such as alkalinity, conjugation, strong metal coordination capability, and hydrogen bond formation capacity, rendering them particularly advantageous for constructing fluorescent probes. The research progress over the past decade on Schiff base-based fluorescent probes for the chemoselective recognition of amino acids is summarized, including the structural features of the probes, recognition mechanisms, and potential applications. Furthermore, the current challenges in the precise recognition of amino acids are analyzed and the key scientific issues that require further exploration are highlighted.

Key words: Schiff base, amino acid, fluorescent probe, chemoselective recognition
