The authors report on the synthesis of two graphitic nanoribbons from the readily available tetrachloro-perylene bisimide. By utilizing sequential Ullmann coupling reactions, the bisimide could be dimerized twice to afford the tetramer. Spectroscopic analyses of the two tetramer products show that 2C as well as either 2A or 2B are formed. Both tetramers show good solubility in common organic solvents.
