Abstract
A simple phosphoryl quinolone (L) based sensor has been synthesized for the selective recognition of Lu by spectrofluorimetric method. In methanol-water (1:1, v/v), the ligand L exhibits a weak emission peak at 400 nm upon excitation at 280 nm. Upon interaction with various f-metal and other selected metals from s, p, and d-block elements, the fluorescence of L is selectively enhanced in the presence of Lu due to the chelation enhanced fluorescence (CHEF) effects. The quantum yield (φ) of L (φ = 0.063) is enhanced to φ = 0.118 upon chelation with Lu ion. From the titration experiment, the limit of detection (LOD) of sensor L to recognize Lu is estimated down to 24.2 nM, which is much lower than the WHO guidelines (76 μM) in drinking water. The formation of host-guest complexation between L and Lu in 2:1 binding stoichiometry is studied by Job's method and the binding constant is estimated by band fit analysis (logK = 5.1). Further, the coordination behaviour between L and Lu is well supported by FT-IR, H NMR, C NMR, P NMR, ESI mass spectral data and the theoretical results.
