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
