Jc. Rodriguezubis et al., SYNTHESIS AND LUMINESCENCE PROPERTIES OF EUROPIUM(III) AND TERBIUM(III) COMPLEXES OF AMINOPOLYCARBOXYLIC ACID LIGANDS CONTAINING 3-AROYLCOUMARIN, Tetrahedron letters, 35(45), 1994, pp. 8461-8464
Three differently substituted 3-aroylcoumarins, L(1-3), with tetraacid
chelating subunits anchored at the 3-benzoyl group were synthesized,
and their complexes with Eu3+ and Tb3+ formed as new potential bioaffi
nity-assay markers. Some spectral and luminescence properties of the c
omplexes in water and methanol are reported.
