Polymer ligands containing a covalently bonded quinolinone fluorophore and COOH (L1) or COONa (L2) binding sites were synthesized by the reaction of high-molecular-weight poly[styrene-alt-(maleic anhydride) ] with 7-amino-4-methylquinolin-2(1H)-one and methanol and subsequent neutralization. The ligand-to-metal energy transfer and ligand binding properties in a series of [Tb(III)-ligand ] complexes were investigated by steady-state and time-resolved luminescence spectroscopy in methanol or deuterated methanol. The intensity of the long-lived terbium(III) ion emission at 490, 545, 585 and 620 n...
