H. Takalo et al., SYNTHESIS AND LUMINESCENCE OF NOVEL EU-III COMPLEXING AGENTS AND LABELS WITH 4-(PHENYLETHYNYL)PYRIDINE SUBUNITS, Helvetica Chimica Acta, 79(3), 1996, pp. 789-802
The synthesis of novel 4-(phenylethynyl)pyridine subunits containing H
2O-soluble complexing agents and their luminescence with Eu-III ions a
re reported. Ligands with high luminescence intensities as well as qua
ntum yields were obtained. Also the prepared labeling reagents as anti
body conjugates gave the highest quantum and luminescence yields repor
ted for H2O-soluble Eu-III labels.
