The four porphodimethene isomers, 5,10‐ and 5,15‐disubstituted, have been synthesized in a one‐pot reaction by the Lindsey protocol. Three of them have been characterized by X‐ray crystallography. Structures show that two of them are 5,15‐porphodimethenes: one is syn ‐equatorial, another is anti ‐configuration; the third one is 5,10‐porphodimethene. In the 5,10‐porphodimethene, the tripyrrane subunit remains planar conformation. 1 H NMR and UV‐vis spectra have also been characterized. Both spectra reveal remarkable difference between 5,10‐ and 5,15‐disubstituted isomers.
