This article focuses on the design,synthesis and monitoring of fluorescent probes for the analysis of iron ions(Fe2+)in extended experimental teaching of analytical chemistry.A new type of fluorescent probe,DCM-Fe,was introduced,which effectively inhibited the occurrence of intramolecular charge transfer by introducing N-oxide groups,achieving fluorescence"turn on"detection of Fe2+.This article also explains how through the design and implementation of this experiment in teaching,students can deeply understand the principles of design and synthesis of fluorescent probes and the application of fluorescence detection technology,and master the synthesis,analysis and application of fluorescent probes in practice,and cultivate students'experimental skills and innovation awareness.This experimental teaching can provide a new idea and method for the extension of analytical chemistry experimental teaching.
