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 6H-benzo[cd]pyrene and related ketones including the first time isolation of the unstable alcohol 6H-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 6H-benzo[cd]pyrene as well as the previously intangible and significantly less stable 5H-benzo[cd]pyrene, the fully conjugated benzo[cd]pyrenyl radical and the ketones as oxidation products.
H-苯并[cd]芘（“奥运烯”）是一种多环芳烃，也是石墨烯的非凯库勒片段。已开发出一种新的合成方法来制备6H-苯并[cd]芘及相关酮类，其中首次分离出了不稳定的醇6H-苯并[cd]芘-6-醇。利用扫描隧道显微镜（STM）和非接触原子力显微镜（NC-AFM）对反应产物进行分子成像，表征了6H-苯并[cd]芘以及之前难以捉摸且稳定性明显较低的5H-苯并[cd]芘、完全共轭的苯并[cd]芘基自由基和作为氧化产物的酮类。
