Living supramolecular polymerization has been utilized as a way to make highly ordered luminescent Pd II molecular chains. In their Communication on page 3089 ff., C.‐M. Che et al. report that by overcoming the energy barrier between two aggregate states (like climbing the mountain shown in the picture), Pd II molecular aggregates will change from a dark kinetically stable state, which is the Pd II dimer pair blocked by counteranions, to a luminescent state with close Pd−Pd contacts showing 1/3 MMLCT absorption/emission.
