以非常简便的方法合成了一类新型的中空芳香螺旋,通过紫外光谱分析发现,此类中空螺旋结构对碱金属离子具有选择性识别作用,并确定了其选择顺序为Rb+ > K+ > Cs+ > Na+ > Li+. 此外,研究了芳香螺旋AH对结合最强的Rb+离子的荧光滴定分析,进一步证实了这类螺旋中空结构对阳离子的通道内识别作用,以及对碱金属离子具有灵敏的响应性.

A novel type of hollow aromatic helices was prepared according to an improved organic synthesis approach. By means of UV-Vis spectroscopy, the recognition and selectivity of aromatic helix (AH) for alkali metal ions were investigated. The results indicated that AH could specifically recognize the alkali metal ions with an order of Rb+ > K+ > Cs+ > Na+ > Li+. In addition, the fluorescence titration was carried out by adding Rb+ into the AH solution, which further underpinned the binding capacity and sensitive responsiveness of AH for the alkali metal ions.

Key words: aromatic helix, hollow channel, alkali metal ions, selective recognition
