利用模板法合成了一种新的含醇羟基西佛碱型大环冠醚 L(7,11-二氮杂 - 3,15 -二氧杂 - 4,5 ;7,10 ;13,14-三苯并环十六 - 6 ,11-二烯 - 1-醇 )的稀土 (除 Sc、Pm)配合物 .经元素分析确定配合物的组成为 L n L2 (NO3) 2 (OH)· n H2 O,配合物的 IR、MS分析反映了其配位情况 ,并确定由模板反应得到了 [1+ 1]型西佛碱大环化合物 .并通过热重和 DSC分析对稀土配合物的热稳定性及热分解性质进行了讨论
A novel alcoholic hydroxy-S & apos; s-base macrocyclic crown ether L (7,11-diaza-3,15-dioxa-4,5; 7,10; 13,14- (Except Sc, Pm) complexes of tribenzocyclohepta-6,11-diene-1-ol were obtained.The elemental composition of the complex was determined as L n L2 (NO3) 2 (OH) H 2 O. The IR and MS analyzes of the complex showed the coordination of the complexes, and confirmed that the [1 + 1] svermectin macrocyclic compound was obtained from the template reaction. The thermal cycloaddition of rare earth complexes Stability and thermal decomposition properties are discussed
