【摘要】 合成了三个新型开链冠醚席夫碱-稀土离子三元配合物RE(H2L)(Mq)(NO3)3,其中RE=Nd3+、Er3+、Yb3+,配体H2L=N,N′-双(邻羟苯亚甲基)-3,6-二氧杂-1,8-二氨基辛烷,Mq为8-羟基喹哪啶。采用元素分析、IR、UV-Vis、热重-差热分析(TG-DTG)等手段对配合物的组成结构进行了表征。抑菌活性实验表明,三种配合物对大肠杆菌有很好的抑菌效果,对金黄色葡萄球菌的抑菌效果较弱。更多还原

【Abstract】 The new complexes of rare earth with noncyclic crown-type schiff base ligand（H₂L,N,N’-bis（salicylidene）-3,6-dioxa-1,8-diaminooctane）and 8-hydroxyquinaldine were synthesized in methanol solution.RE（H₂L）（Mq）（NO₃）₃（RE=Nd,Er,Yb）were determined by elemental analysis,IR,UV-Vis.The results indicate that the H₂L is bonded to RE 3+ in hexadentate via two phenolic hydroxyl oxygen atoms,two nitrogen atoms of schiff base and two oxygen atoms of the aliphatic C—O—C group.The antibacterial activities of complexes were investigated,and the results show that the complexes have selected antibacterial activities.更多还原
