Abstract
The anti-symmetric behaviour of cyclohepta-fused and cyclopenta-fused PAHs make these two annealed odd-membered rings interesting moieties to combine and fuse on the same aromatic perimeter, e.g. pyrene. The synthesis of cyclopenta-cycloheptapyrene 11 is attempted with different synthetic strategies, making use of pyrene (1) and 1,2,3,6,7,8-hexahydropyrene (2) as precursors. However, the
