H-Benzo[ cd]pyrene ('Olympicene′) is a polyaromatic hydrocarbon and non-Kekulé fragment of graphene. A new synthetic method has been developed for the formation of 6 H-benzo[ cd]pyrene and related ketones including the first time isolation of the unstable alcohol 6 H-benzo[ cd]pyren-6-ol. Molecular imaging of the reaction products with scanning tunnelling microscopy (STM) and non-contact atomic force microscopy (NC-AFM) characterised the 6 H-benzo[ cd]pyrene as well as the previously intangible and significantly less stable 5 H-benzo[ cd]pyrene, the fully conjugated benzo[ cd]pyrenyl radical and the ketones as oxidation products.
