摘要 合成了两种β-二酮缩芳胺型双席夫碱化合物,双乙酰丙酮缩1,5-萘二胺和双苯甲酰丙酮缩1,5-萘二胺,利用紫外-可见吸收光谱研究了两种化合物对不同金属阳离子的识别作用.锌离子的加入使得两种化合物在DMSO-H2O溶液(1∶1,V∶V)中的紫外-可见吸收强度均有显著增强,而其它金属离子的加入对化合物的紫外-可见吸收光谱均无明显影响,说明这两种化合物对锌离子都有很好的识别作用. Two β-diketone aromatic amine Schiff bases were synthesized by the reactions of 1,5-naph- thalenediamine with pentane-2,4-dione and 1-phenylbutane- 1,3-dione, respectively. The UV-vis spectra re- vealed that both of the two compounds had highly selective responses to Zn2+.In DMSO-H20( 1:1 ,V :V) so- lutions,Zn2+ induced dramatic enhancements in the UV-vis spectra of the two compounds,whereas the other metal ions had no obvious influence.
