Invited for this month's cover is the group of Prof. Fabrizio Mancin from the University of Padova, Italy. The cover picture shows an 18‐crown‐6‐functionalized gold nanoparticle that switches its molecular recognition preference from organic cations to organic anions in the presence of potassium ions, thus allowing 1 H NMR sensing of potassium.
