Meet at the border : Assembly of the water‐soluble cobalt tetrakis( N ‐methylpyridinium‐4‐yl)porphyrin [CoTMPyP] 4+ at soft interfaces is enhanced and stabilized by its interfacial interaction with the lipophilic anion (C 6 F 5 ) 4 B − . The supramolecular structure thus formed (see picture) provides excellent catalytic activity in the four‐electron reduction of oxygen.
