Monodisperse, rodlike molecules 1 composed of repeating individual chromophores that have substantial electronic interactions in the ground state have been synthesized by the meso – meso coupling of porphyrins. The 128‐mer ( n =63) at about 106 nm long is the longest such system known. The S 1 states are delocalized over 6 – 8 porphyrin units. Ar=3,5‐dioctyloxyphenyl.
