The synthesis of three octapyrrolic, 8-10, and four dodecapyrrolic, 15-18, oligomers is reported. They are linear poly(dipyrromethene)s and potential ligands as building blocks for supramolecular architectures through self-assembly. Octapyrrolic oligomers 8-10 were prepared in 90-95% yields by condensation of 2 equiv of a tripyrrolic compound 4 with 1 equiv of diformyldipyrrolic compounds 5-7. A similar procedure, involving the condensation of 2 equiv of a pentapyrrolic starting material 13 with 1 equiv of 5-7 or 14, was found to give rise to the corresponding dodecameric systems 15-18 in 41-56% yields.
