| 中文摘要: |
| 设计合成了基于吲哚酰腙的钳形阴离子受体1,UV-vis 滴定实验表明1在含1% DMSO的CH3CN 溶液中能选择性识别具有重要生物学意义的F-、AcO- 和H2PO4-离子(结合比均为1:1且Ka > 104 M-1),但对Cl-、Br-、I-、NO3-、N3-、HSO4- 和ClO4- 无识别作用。与1相比,只含酰腙NH的参照化合物2在同样溶剂中对上述三种阴离子的亲和性明显减弱,尤其是对H2PO4-离子。核磁滴定实验表明,受体1能协同使用吲哚NH和酰腙NH从而对阴离子产生了强效键合作用。 |
| 英文摘要: |
| An indole-acylhydrazone-based tweezer-shaped anion receptor (1) was designed and synthesized, and it displayed a selective recognition for biologically important F-, AcO- and H2PO4- (Ka > 104 M-1 with a 1:1 stoichiometry) in CH3CN containing 1% (v/v) DMSO. However, no binding interaction was observed for other anions such as Cl-, Br-, I-, NO3-, N3-, HSO4- and ClO4-. Compared with receptor 1, reference compound 2 (only with acylhydrazone NH) showed a decreased affinity towards the above three anions under the same solvent system, especially for H2PO4-. 1H NMR titration experiments indicated that cooperative use of indole NH and acylhydrazone NH in receptor 1 led to a strong binding with anions. |
