| Abstract: | Caterpillar-motion like rotational isomerization of meso-aryl substituted 26]- and 28]hexaphyrins has been revealed for the first time. Two-electron oxidation and reduction induce reversible interconversion between N,N'-dimethyl 26]- and 28]hexaphyrins with a rotational isomerization, in which the N-methylated pyrroles move from the corner in the former to the centre in the latter. |
