Significance

The authors’ interest in processable  polynaphthalenes  led  them  to  consider N-annulated variants with compound 3 as a suitable small molecule target. The nitrogen atom increases the electron density of the aromatic system making oxidative dimerization and cyclization easier,   while  the  alkyl  substituent  of  the  amine increases solubility and processability. The synthesis of 3 was accomplished from the readily available N-annulated perylene 1 in a single, low-yielding step or via a higher-yielding two-step sequence.
