title: Unprecedented non-aromatic, conformationally locked dibenzohexaphyrin analogs carrying multiple meso-exocyclic double bonds.
abstract: Acid-catalysed, '3+3' condensation of m-bispyrryl benzene derivatives with acetone afforded new non-aromatic macrocycles that can be converted to meso-alkylidenyl dibenzohexaphyrins carrying four exocyclic double bonds at meso-positions by DDQ oxidation.
