摘要:

基于阴离子识别研究的理念,我们合理地设计了一种新型的阴离子受体——β-NAAB。通过紫外可见吸收光谱观察不同阴离子最大吸收峰的变化情况。结果发现:由于离子半径的增大导致体系的自组装堆积,以及分子间的交联产生局部屏蔽效应导致部分阴离子的紫外-可见吸收光谱发生了蓝移现象。同时,发现以混合溶剂(20%DMSO和80%H2O)为良溶剂的所有阴离子溶液中,只有PF-6的溶液有荧光发射峰,这说明β-NAAB在混合溶剂(20%DMSO和80%H2O)中对F-6有特殊的识别能力。

Abstract:

Based on the concept of anion recognition research, we had designed a new type of anionic receptor-β-NAAB. The changes of maximum absorption peaks of different anions were observed by UV-visible absorption spectra.Due to the increase of ion radius,the self-assembly accumulation of the system and the partial shielding effect of intermolecular cross-linking resulted in the UV-vis absorption spectra of partial anions were occurred blue shift.At the same time,we found that of all anionic solutions with mixed solvent (20% DMSO and 80% H2O) with no fluorescence intensity, only the solution of PFF-6 had fluorescence emission peaks,and this indicates that β-NAAB has special ability to recognize PFF-6 in mixed solvents (20% DMSO and 80% H2O).
