In order to combine the merits of rare earth organic complexes with excellent material performances of polymers,a polymerizable chelating agent,3-allyl-2,4-pentane dione(APD),was synthesized by phase transfer catalysis and its rare earth complexes were prepared.The compounds were characterized by EA,IR and 1H NMR.Their UV spectra and fluorescence spectra were investigated.The effects of allyl on the luminescence properties of the complexes were studied.The results show that the sensitization of APD is changed by allyl in comparison with that of acetyl acetone(acac),and it becomes an ideal novel ligand of Eu.In addition,intramolecular energy transfer mechanism in the luminescence process in the complexes was also discussed in detail.
