Ring a ring of benzenes : An unsubstituted N‐confused metalloporphyrin forms both C 3 ‐ and C 1 ‐symmetric trimers in solution, whereas its monophenyl‐substituted analogue forms exclusively C 3 ‐symmetric trimers (see picture) owing to significant stabilizing noncovalent interactions between the three phenyl groups, as evaluated both experimentally and theoretically.
