Oxidation at position 10 converts the title compounds into dimers. In an extension of this reaction a 15,15′-p-phenylene-linked bis(oxophlorin) produces the robust supramolecular array tetrakis(isooxophlorin) 1. In the crystal 1 has an overall helical structure in which the groove is filled by molecules of n-hexane.
