The twofoldHeckreaction of the vinylpyrroles 3a and 3b with the iodobenzenes 4a-c led to the linear pyrrole oligomers 5, 6, and 7. The synthesis of both symmetrical and unsymmetrical oligomers, such as 10a and 10b, was also accomplished by a Heckreaction of 8 and 9 and by a Heckreaction of 3a and 11 followed by a Wittig reaction and a second Heckreaction with 8. The pentacyclic oligomers 14 and
