title: A novel 2-(2-Formyl-4-methyl-phenoxy)-N-phenyl-acetamide-based fluorescence turn-on chemosensor for selenium determination with high selectivity and sensitivity.
abstract: A novel turn-on fluorescent chemosensor, 2-(2-Formyl-4-methyl-phenoxy)-N-phenyl-acetamide (FMPPA) was designed and synthesized, and its photophysical properties were characterized. Upon coordination with Se (IV), the chemosensor showed incredible fluorescence enhancement (turn-on), other alkali, alkaline earth, transitional metal ions, and common anions including Li(+), Na(+), K(+), Rb(+), Cs(+), Be(2+), Mg(2+), Ca(2+), Sr(2+), Ba(2+), Ni(2+), Cu(2+), Cd(2+), Zn(2+), Mn(2+), As(3+), Pt(4+), V(5+), Fe(3+), Mo(6+), Al(3+), CO3(2-), Cl(-), SCN(-), AC(-), NO3(-), F(-), SO4(2-) had no significant interference on Se (IV) determination. The chemosensor exhibits a dynamic response range for Se (IV) from 3.32 × 10(-7) to 2.63 × 10(-6)M, with a detection limit of 9.38 × 10(-9)M (3σ).
