| 摘 要： | 合成了一种新型的带有双蒽基团的酰胺阴离子受体B.用荧光光谱、紫外-可见吸收光谱以及核磁共振氢谱研究了B与Cl-,Br-,I-及对硝基酚氧阴离子的相互作用.结果表明,B与Cl-,Br-,I-等阴离子无识别作用,而与对硝基酚氧阴离子有较好的选择性识别能力,其络合比为1∶1.利用荧光发射强度和吸光度的变化分别计算出主体B与客体相互作用的络合常数KS分别为(1.24±0.07)×105和(1.27±0.18)×105,并对主体分子B与客体之间的相互作用进行了讨论.

| Abstract: | Anovel amide anion receptor Bbearing two anthracene substituents was synthesized.The interaction between Band various anions(Cl-, Br-, I-, p-O2NC6H4O-) was studied by fluorescence spectrum, UV-Vis spectruMAnd1H NMR.The results demonstrate that Bexhibited a more significantly selective recognition for p-O2NC6H4O-than the other anions(Cl-, Br-, I-Band p-O2NC6H4O-formed 1: 1 mplex.The stability constant was calculated by variation in absorbance and fluorescent emission intensity.The mechanism of the interaction between Band p-O2NC6H4O-was preliminarily studied. |
