Five ternary complexes have been synthesized from europium with aromatic carboxylic acid(p-methylbenzoic acid, methoxybenzoic acid, m-chlorobenzoic acid, benzoic acid, p-hydroxylbenzoic acid) and acrylamide; and also characterized by means of elemental analysis, thermal analysis, FT-IR spectra and UV spectra. Fluorescence spectra show five ternary complexes have nice luminescent properties, the sequence of ability that the aromatic carboxylic acids transfer light energy to europium ion is as follows: benzoic acid > p-methylbenzoic acid > methoxybenzoic acid > m-chlorobenzoic acid > p-hydroxylbenzoic acid. At the same time, the ternary europium complexes containing a reactive ligand acrylamide will possibly have potential application on the fabrication of bonding-type europium polymer luminescent materials.
