| 摘 要： | 设计合成了荧光传感分子α-呋喃甲醛缩对苯二甲酰腙(p-PB-Fu),采用1H NMR对其结构进行了表征,应用吸收和荧光光谱初步探讨了在乙腈中其对Cu2+的响应.结果表明,p-PB-Fu与Cu2+存在两个结合过程,首先是其与Cu2+以2:1的方式形成普通配合物;而随着Cu2+的继续加入,所形成的配合物之间通过自簇集而形成金属配位聚合物/寡聚物.光谱数据初步表明后者对Cu2+具有较高的识别选择性.

| Abstract: | A novel bis(furan-2-ylmethylene)terephthaloyl-hydrazone(p-PB-Fu) was synthesized and its structure were characterized by 1H NMR.Its interaction with Cu2+ in acetonitrile was preliminary investigated by using absorbance and fluorescence spectroscopy.The results showed that p-PB-Fu coordinated with Cu2+ being two steps.Firstly,p-PB-Fu coordinated with Cu2+ to form 1:1 complex,secondly,p-PB-Fu as bidentate ligands to form metal coordination polymer/oligomer along with increasing of Cu2+.Spectral evidences supp... |
