In organic chemistry, the acenes or polyacenes are a class of organic compounds and polycyclic aromatic hydrocarbons made up of benzene rings which have been linearly fused. They follow the general molecular formula C4n+2H2n+4.
Larger acenes
Due to their increased conjugation length the larger acenes are also studied. for the first time. Four years later, in the beginning of 2024, Ruan et al. succeeded in synthesizing unsubstituted tridecacene (n=13) on a (111)-gold surface. The acene was characterized by STM- and STS-measurements. ==Related compounds==

The acene series have the consecutive rings linked in a linear chain, but other chain linkages are possible. The phenacenes have a zig-zag structure and the helicenes have a helical structure.
