Cyclotetramerization of a hydroxymethylphenanthropyrrole afforded a highly conjugated porphyrin 1 with four annelated phenanthrene rings. The 68 carbon atoms in the dication of this highly symmetrical heptadecacycle–the neutral compound is virtually insoluble in most organic solvents–produced only nine resonances in the 13C NMR spectrum.
