The preparation of several covalently linked [6]-heliceneporphyrins is reported. A fused [6]-helicene-porphyrin p-extended aromatic system was isolated, the enantiomers separated and the chiroptical properties determined. The oxidative cyclodehydrogenation proved to be very effective for six-membered fused helical systems, but not suited for the formation of five-membered fused systems.
