Three ligands 2,2′-[2,3-naphthylenebis(oxy)]-bis(N,N-diethyl(acetamide)) (La), 2,2′-[2,3-naphthylenebis(oxy)]-bis(N,N-diisopropyl(acetamide)) (Lb) and 2,2′-[2,3-naphthylenebis(oxy)]-bis(N,N-dibutyl(acetamide)) (Lc) and their europium(III) nitrate complexes were synthesized. The complexes were characterized by elemental analysis, IR, fluorescence spectroscopy and conductivity. The europium atoms are coordinated by O-atoms from C{double bond, long}O, Ar-O-C. With the difference of the ligands, the solid fluorescent intensities of the Eu complexes vary regularly. Some factors that influencing the fluorescent intensity were discussed.
