meso-Tetrakis[4-(heptyloxy)phenyl]porphyrin.

The core of the novel title centrosymmetric porphyrin derivative, C72H86N4O4, with long flexible hexyloxy substituents, is almost planar, which is anticipated to facilitate π-electron delocalization and lead to a significant deviation between the planes of the benzene rings and the molecular plane. The two N-bound H atoms on the pyrrole rings are disordered and the occupancy factors refined to a ratio of 0.28 (2):0.72 (2).
