A europium (III) complex-based surface fluorescence sensor for the determination of uranium (VI)

Two Fe(iii)/Eu(iii) Salophen complex-based optical sensors for determination of organophosphorus pesticide monocrotophos

“…[23][24][25][26][27][28] Meanwhile, there have been numerous research studies about sensors based on Schiff base metal complexes up to now. [25][26][27][29][30][31][32] In this study, two novel optical sensors for MP detection were created using the Fe(III) Salophen complex and Eu(III) Salophen complex, respectively. For the Fe(III) Salophen complex, due to the ultra-high affinity between Fe 3+ and the phospholipid group, 33 the coordination site at the Fe(III) metal was partly replaced, forming P=O-Fe bonds with the phospholipid group.…”

“…Meanwhile, the nitro group in the Fe(III) Salophen complex was combined with the amino in MP by a hydrogen bond to form a supramolecule complex, causing the system to generate a strong RLS signal at 300 nm. For the Eu(III) Salophen complex and 5-aminouorescein derivatives, the Eu(III) Salophen complex was immobilized on the surface of Sigel-NH 2 particles as the solid phase receptor of MP based on the ultra-high affinity between Eu 3+ and the phospholipid group 29,34 and 5-aminouorescein derivatives as the uorescently labeled receptor of MP, which can selectively bind the MP and form a sandwich-type supramolecule. Finally, the proposed two methods have been used to detect MP in real samples such as tap water and camellia oil (Scheme 1).…”
