Engineered Fluorescent Ionic Liquids with Tunable Cationic Architecture for Charge Delocalization-Driven Al3+ Recognition and Real-Sample Analysis
Fluorescent ionic liquids (FILs) provide a versatile platform for metal ion sensing; however, the role of cationic structure in governing sensing efficiency remains underexplored. Herein, we report two 8-hydroxyquinoline-based FIL probes incorporating imidazolium (compound 1) and pyridinium (compound 2) frameworks fo...
