Ungleich geteilt: Die kooperative CuII- und BIII-Metallierung von meso-Heptakis(pentafluorphenyl)[32]heptaphyrin (1) löst eine Extrusion aus, die zu BIII-meso-Tris(pentafluorphenyl)[14]subporphyrin (2) und einem CuII-Porphyrin (3-Cu) führt. Die optischen Eigenschaften des Subporphyrins 2 spiegeln die eingeschränkten Rotationsmöglichkeiten der elektronenziehenden Substituenten wider.
