An optical material for the detection of β-hydroxybutyrate based on a terbium complex
Source abstract
Abstract
A novel Tb3+ complex (Tb(C14H10O4)⋅Cl, TbL2) based on benzoic acid (L+H) was successfully synthesized, and gave a weak green emission in methanol–water (V:V, 4:1, pH 4.49). With the addition of β-hydroxybutyrate (β-HB) to a semi-aqueous solution of TbL2, an increment of the luminescent intensity at 545 nm assigned to 5D4 → 7F5 transition of Tb3+ was measured, which was evident to the naked eye. The response showed high selectivity for β-HB compared with other common anions including Cl−, NO3-, CO32-, PO43-, HPO42-, H2PO4-, C2O42-, P2O74-, SO42-, lactate, AcO−, citrate, malate therefore it has the potential to be applied as a luminescent sensor for β-HB.
