Highly K+‐Selective Fluorescent Probes for Lifetime Sensing of K+ in Living Cells

Abstract Invited for the cover of this issue is the groups of Pablo Wessig and Hans‐Jürgen Holdt at the University of Potsdam. The image depicts a fluorescent probe consisting of the highly K + ‐selective N ‐( o ‐isopropoxy)phenylaza‐18‐crown‐6 ionophore and the bright [1,3]dioxolo[4,5‐ f ][1,3]benzodioxole fluorophore.
