An undecacyclic carbon-centered hydrocarbon radical: synthesis and investigation
A stable, cyclopenta-fused polyaromatic hydrocarbon (CP-PAH) radical, comprising six six-membered and five five-membered rings alternately fused within an undecacyclic framework, was synthesized via ortho-fusion of a suitably o,o’-substituted difluorenylfluorene, followed by establishment of the π-conjugated system.
