A design concept of planar conjugated ladder oligomers of perylene bisimides and efficient synthetic strategy via regioselective photocyclization.
By photocyclization, benzene, thieno[3,2-b]thiophene, and fluorene units were embedded between the two perylene units. Symmetric oligomeric perylene bisimide 6 displays broad absorption and strong electron-accepting ability.
