Abstract

A meso, meso-diketohexaphyrin was isolated and characterized as a chemically stable non-Kekulé singlet biradicaloid. Two unpaired electrons are seemingly delocalized on two tripyrrolic units separated by C-O bonds. These results underscore the potential of expanded porphyrins to achieve unique electronic states.
