The change in ring current of octaethylporphyrin, meso-tetraphenylporphyrin and phthalocyanine cobalt(II1) complexes with axial amine ligands was studied using a double dipole network model. The porphyrin ring current was found to be highest in octaethylporphyrin but decreased by 5% in meso-tetraphe

## Abstract The facile preparation of zinc(II) __meso__‐tetraphenylporphyrin (Zn TPP) and derivatives from substituted benzaldehydes and pyrrole, combined with the calculation of ring current shifts in these molecules, provides a useful series of selective diamagnetic shift reagents. The porphyrin‐
