合成了稀土与姜黄素和1,10-菲啰啉的稀土三元配合物和稀土与姜黄素的稀土二元配合物, 通过元素分析、摩尔电导、热重-差热分析、 IR 、 UV-Vis 和1H NMR方法, 确定配合物的化学组成分别为: REL3L′及REL3 · 2H2O (RE=Sm, Eu, Dy, L=姜黄素, L′=1,10-菲啰啉). 同时研究了配合物在室温下的荧光性质, 结果显示稀土三元、 二元配合物都表现出配体(L)的特征发射且发射强度大于配体(L), 三元配合物的荧光强于二元配合物. 抗菌活性试验结果表明, 稀土三元、 二元配合物对枯草杆菌和大肠杆菌都表现出很好的抑制作用, 而且稀土三元配合物REL3L′对所选菌种的抑菌性明显强于稀土二元配合物REL3 · 2H2O和配体姜黄素.
