一种树状桥联水杨醛亚胺配体的合成与表征

摘要

以甲醇为溶剂,将具有配位能力的水杨醛(2)通过Schiff碱缩合反应接枝到整代聚酰胺-胺(1)骨架上,合成了一种树状桥联水杨醛亚胺配体,其结构经1H NMR,IR和元素分析表征.最佳反应条件为:1 4 mmol,n(1):n(2)=1:6,甲醇30 mL,于65℃反应5 h,产率在90%以上.%A dendritic bridged salicylaldehyde-imine ligand were synthesized by Schiff-base condensation reaction of salicylaldehyde (2) grated to the first generation poly (amidoamine) dendrimer ( 1 )in methanol. The structure was characterized by 1H NMR, IR and elemental analysis. The optimum reactions at 65 ℃ for 5 h were as follows: 1 was 4 mmol; n ( 1 ): n (2)= 1: 6; methanol was 30 mL.The yield can be up to 90％ under the optimum reactions.
