The cooperative self‐assembly of chiral zinc porphyrins is regulated by a photoresponsive phenylazopyridine ligand ( 1 ; see picture). Porphyrin stacks depolymerize into dimers upon axial ligation and the strength of the coordination is regulated by its photoinduced isomerization, which shows more than 95 % conversion ratio for both photostationary states.
