摘要：
Highly fluorescent Eu-polymer complexes were synthesized through copolymerization of EuPhen (Nap)(2)AA with methyl methacrylate or styrene and their luminescent properties were investigated. The Eu-polymer luminophores showed intense red emission under UV excitation, and the emission intensities were much stronger than that of the EuPhen(Nap)(2)AA complex. Typical relationships between emission intensity and Eu content in copolymers exhibited some extent of concentration quenching in our studies. However, D-5(0) lifetime results suggested that the concentration quenching phenomena cannot be accounted for by deactivation of the D-5(0) state through exchange and multipolar interactions. Ligand energy migration along or crosspolymer chains can interpret the emission concentration quenching phenomena reasonably. (C) 1997 John Wiley & Sons, Inc.
