Mix and match: The title porphyrinoid has been synthesized and shows unique coordination chemistry by incorporating two differentmetals with differentoxidationstates (see figure). X‐ray crystallography was used to confirm that a rectangular conformation in both mono‐ and binuclear complexes was retained.
Eight-figured chirality: A novel [36]octaphyrin analogue embedding two N-confused pyrrole units demonstrates unique prototropy-coupled isomerization. Upon bis-metal complexation, fully π-conjugated, helical Figure-of-eight structures are realized. Distinct CD response in the NIR region confirms chirogenesis of the helical enantiomers.
