Fluorescent Detection Probes for Hg²⁺ and Zn²⁺ with Schiff Base Structure Based on a Turn-On ESIPT–CHEF Mechanism

Three Schiff base fluorescent probes <b>3a</b>–<b>3c</b> with <i>N</i>-heterocyclic structure were designed and synthesized by using the reaction of 4-diethylaminosalicylaldehyde with different <i>N</i>-heterocyclic amines, such as 2-aminobenzimidazole, 2-aminobenzothiazole, and 2-amino-6-methylpyri...
