Abstract
Three binary europium complexes with benzoic acid and ortho (meta) methylbenzoic acids in the first stage. Then, these complexes were introduced into 4-vinyl pyridine-ethyl methacrylate co-polymer hosts using the former component as the second ligand. The composition of the hybrids was characterized by FT-IR and the photophysical property of them was investigated by UV spectra, luminescent spectra and luminescent lifetimes. The experiment results substantiate that 4-vinyl pyridine could co-ordinate to europium ions effectively with nitrogen atoms of the pyridine ring. Therefore, the intramolecular energy transfer process accomplished within polymer hybrids and red emissions of Eu3+ have been obtained.
