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 S1 states are delocalized over 6-8 porphyrin units. Ar = 3,5-dioctyloxyphenyl.
