Abstract

Singly N-confused [26] and [28]hexaphyrins (4, 5) with planar and twisted structures, respectively, were prepared via the acid catalyzed [3 + 3] condensation of N-confused and regular tripyrrane precursors. Hückel aromaticity is observed for [26]hexaphyrin, while the [28]hexaphyrin and its mono-Pd(ii) complex exhibit "nonaromaticity" in spite of their Möbius-type structures, judging from the spectroscopic features and theoretical calculations.
