A new ligand, 1,2-bis[(2-benzyloxy)benzoylamino]ethane, and its complexes of europium and terbium have been synthesised and characterised. Under UV light, the europium and terbium complexes exhibited characteristic emissions and measurement of the lowest triplet state energy level of the ligand indicates that it matches better to the lowest resonance energy level of the Tb(III) ion than to that of the Eu(III) ion.
