Luminescent Sensor for Carbonate Ion Based on Lanthanide(III) Complexes of 1,4,7,10-Tetraazacyclododecane-1,4,7-Triacetic Acid (DO3A)
Original language description
Lanthanide(III) complexes of 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid (H(3)DO3A) are suggested as sensors for sensitive luminescence-based determination of a carbonate anion. Thermodynamic study of association of [Eu(H2O)(2)(DO3A)] with bidentate anionic ligands using luminescence spectroscopy reveals an affinity order CO (3) (2-) > oxalate(2-) > picolinate(-) > phthalate(2-) a parts per thousand citrate(3-); presumably as a consequence of an increasing chelate ring size. The ternary [Eu(DO3A)(picolinate)](-) and [Tb(DO3A)(picolinate)](-) complexes show improved photophysical properties due to the antenna effect of the picolinate anion. High quenching effect of carbonate anion and, to a lesser extent also oxalate, enables construction of a linear calibration plot utilizing optimized experimental conditions (e.g. c (LnL) = 0.1 mM, c (picolinate) = 2-5 mM, pH = 7.4, lambda (exc) = 286 nm, etc.) for carbonate determination in solution. Both sensors show a comparable sensitivity
