摘　　要：合成并表征了两种铕 苯甲酰环酮 邻菲罗啉三元螯合物EuL3Phen (L =2 苯甲酰环己酮 (BCH) ,L′ =2 苯甲酰 1 萘满酮 (BT) ,Phen =1,10 邻菲罗啉 )。研究了二者在固体和溶液下的荧光性质及其溶液的紫外光谱性质。结果表明 ,两种铕螯合物都能发射出铕离子的特征红色荧光 ,其中Eu(BT) 3Phen的荧光性能最佳。Two europium complexes Eu(BCT) 3Phen and Eu(BT) 3Phen,which contained ligands 2 benzoyl cyclohexanone(BCH),2 benzoyl 1 tetralone(BT) and phenanthroline(Phen),were synthesized and characterized. Their UV and fluorescent properties were studied. The results show that both of two europium chelates emit red fluorescence with europium ion characteristics, in which Eu(BT) 3Phen has better fluorescent property.
