Recent progress in high linearly fused polycyclic conjugated hydrocarbons (PCHs, n > 6) with well‐defined structures

Although polycyclic conjugated hydrocarbons (PCHs) and their analogues have gained great progress in the fields of organic photoelectronic materials, the in‐depth study on present PCHs is still limited to hexacene or below because longer PCHs are insoluble, unstable, and tediously synthesized. Very...
