✦ Synopsis

The polyac rylic acid derivative, the copolymer (PABAM) of acrylic acid (AA) and p-benzoic acid acrylamide (BAM) were prepared by polymeric reaction. The coordinate structure of the polymer-Eu3+ complexes was characterized by X-ray photoelectron spectroscopy. The fluorescence intensity of the PABAM-Eu3+ complex was enhanced because of introduction of a BAM unit in the polyacrylic acid and reached a maximum when the mole ratio of AA to BAM was about 1 : l .

The ternary complexes of Eu3+-polymer-l,10phenanthroline (PRL), or 2,2-bipyridine (BPD) were synthesized. The polymers used were PABAM and polyacrylic acid (PAA). The fluorescence intensity of the polymer-Eu3+ complexes was increased by 5 -21 times owing to the introduction of PRL and BPD.
