hole-hopping) in covalently linked porphyrin arrays prompted the development and application of methodology for the synthesis of β-linked porphyrin dimers. Reaction of a β-substituted pyrrole with 2-hydroxymethylpyrrole led to the dipyrromethane bearing a single β-substituent and no meso- nor α-substituents. Condensation of the β-substituted dipyrromethane with an aldehyde and a meso-substituted dipyrromethane
