A Eu-polymer complex containing Eu(13A)3phen (BA stands for benzoic acid and phen is 1,10-phenanthmline) and epoxy resin was synthesized in. It was found that the emission light color under 254 nm UV light could change reversibly between red and blue with addition and evaporation of acetone in the Eu-polymer complex. To explain the reversibility of the emission color, the chemical structure and fluorescence property of the complexes were investigated using FTIR, UV-vis, and photoluminescence (PL) spectra. It is proposed that the competitive coordination between Ett/epo.x-y and Ett/acetone was responsible for the reversible emission color change.
