摘要
合成了一种新型的含蒽荧光基团和酰肼结构的阴离子受体,经过核磁共振氢谱(1HNMR)、质谱(MS)、红外光谱(IR)等检测方法证实其结构.用荧光光谱法研究了该阴离子受体与不同阴离子(AcO-,H2PO-4,Cl-,Br-,I-)的相互作用.结果表明:该阴离子受体与AcO-具有很好的选择性识别配位性能,对不同阴离子的络合选择性次序为:AcO->H2PO-4形成1∶1的络4 Cl-,Br-,I-.荧光光谱数据说明该阴离子受体可与AcO-,H2PO-合物.
A novel anion receptor bearing anthracene flurophore and acyl-hydrazine was synthesized and identified by ()~1H NMR,MS,IR and elemental analysis.The interaction between the receptor and various anions(AcO^(-),H_(2)PO^-_4,Cl^(-),Br^(-)and I^(-))was studied by fluorescence spectrum.The results demonstrate that the receptor had an excellent selective recognition for AcO^-. The receptor bounds anions with a selectivity in the order of AcO^(-)>H_(2)PO^-_4Cl^(-),Br^(- )and I^(-). The obtained fluorescence data indicate that a 1∶1 stoichiometry complex is formed between the receptor and AcO^(-)or H_(2)PO^-_4.
