The title compound, C48H20F19N4O3P, prepared by the nucleophilic attack of triethyl phosphite on one of the 4‐fluoro atoms of 5,10,15,20‐tetrakis(pentafluorophenyl)porphyrin, contains a single molecule in the asymmetric unit. The porphyrin unit is almost planar [largest non‐H atom deviation = 0.174 (6) Å], and has the planes of the neighbouring benzene rings oriented at angles ranging from 64.3 (2) to 89.6 (3)° relative to the porphyrin core. The P=O group is almost coplanar with the attached benzene ring, subtending an angle of 4.0 (3)°. Several weak supramolecular interactions, namely C—H...π, C—F...π, P=O...π, C—H...(O,F) and F...F contacts, contribute to the crystal packing.
