Significance

A new way to achieve complexes that exhibit Möbius aromaticity is described. Conjugated oligopyrrolic macrocycles (also known as expanded porphyrins) were locked into a twisted Möbius strip conformation using group 10 metals. Experimental and numerical studies reveal compounds 3, 5, and 7-9 as conformationally locked Möbius aromatic molecules.
