Zusammenfassung:The stabilization of G‐quadruplexes by means of K+ ions, and the separation of the nanostructures by 18‐crown‐6 or [2.2.2] cryptand, provide means to assemble switchable photonic or electrocatalytic molecular systems. On page 3654, this is exemplified with the construction of a G‐quadruplex‐based photonic “DNA spring” by I. Willner and co‐workers, and by the assembly of a switchable hemin/G‐quadruplex nanostructure on an electrode, acting as an electrocatalytic “ON”/“OFF” switch towards the reduction of H2O2.
