摘要：

[GRAPHICS] The tunable interconversion between two highly ordered supramolecular motifs (G-quartet K+-templated column and G-ribbon) of a lipophilic guanosine derivative fueled by cation complexation and release in a cryptand [2.2.2] containing guanosine solution is reported. The process is controlled by the sequential addition of acid and base.
