The Suzuki cross-coupling reaction of copper beta-octabromo-meso-triarylcorroles with arylboronic acids led to various copper peraryl-substituted corroles 4ac, 5ac, and 6ac. The crystal structures of complexes 4b, 5a, 5b, 6a, 6b, and 6c show that their saddling dihedral angles strongly depend on the nature of the meso substituents, whereas the beta-aryl substituents induce a significant redshift of their UV/Vis absorption maxima. Copper corrole 5c was successfully demetalated to produce the corresponding undecaarylcorrole free base 7. The crystal structure of 7 revealed that the introduction of 11 bulky aryl groups on the corrole ring did not produce unusual distortions in the macrocycle of the free base.
