meso‐meso , ß‐ß, ß‐ß Triply‐linked zinc(II) porphyrin tapes were synthesized by powerful oxidation of meso‐meso ‐linked zinc(II) porphyrin arrays up to tetramers with DDQ‐Sc(OTf) 3 . Coordination of butylamine to zinc(II) ions of porphyrin rings dissociates their aggregation, resulting in clear NMR spectra and sharper red‐shifted absorption bands.
