Derived from a Pd-catalyzed oxidative C–H/C–H coupling reaction, two giant imidazole-based [60]­tetradecaphyrins adopting stable figure-eight geometry together with one [30]­heptaphyrin are obtained by [5 + 2] MacDonald condensations in one pot. The directional imidazole is believed to play a vital role for the diverse cyclization and conformation stabilization.
