We report the synthesis and characterization of a meso-meso directly linked bisporphyrin 6 bearing both alkyl and aryl residues. Its oxidative fusing results in the corresponding meso-meso β -β ,β -β - linked bisporphyrin. The first crystal structure analysis of a meso-meso directly linked porphyrin dimer (6) has shown the inequivalency of the two porphyrin units with regard to the macrocycle conformation. Quite distinct mixings of distortion modes were observed for the two aromatic macrocycles.
