摘要：

Orthogonal and twisted dimers of pyrrole-fused pentaazapolycyclic hydrocarbons (pentaazacoronene analogs) were synthesized, linked either directly or by phenylenes. Although the dimers and the reference monomer did not have any substituents at the a-positions of the terminal pyrroles, two reversible oxidation waves were observed in the cyclic voltammograms. ESR measurements of the chemically generated dications of the dimers showed typical radical cation signals, indicating successful accumulation of the redox activity of the pentaazacoronene analog.
