A novel 2-(2-Formyl-4-methyl-phenoxy)-N-phenyl-acetamide-based fluorescence turn-on chemosensor for selenium determination with high selectivity and sensitivity

- A novel compound FMPPA was designed and synthesized as Se (IV) chemosensor.
- A fluorescent enhancement signal was observed when FMPPA combined with Se (IV).
- A good sensitivity and selectivity for Se (IV) determination was achieved.
