Abstract

A method was proposed for the synthesis of Eu(III) compounds with para-methoxycinnamic acid anions and neutral ligands, starting from the sodium salt of para-methoxycinnamic acid. Using the methods of chemical elemental and thermal analyses and IR spectroscopy, the composition of the complexes and the coordination mode of carboxylate anions were determined. It was found that europium(III) methoxycinnamate with hexamethylphosphotriamide has the highest luminescence intensity. Luminescent polymer materials with synthesized europium(III) methoxycinnamates were obtained.
