A series of 9-phenylcarbazoles have been synthesized and characterized for their electrochemical as well as spectral properties. For 3,6-substituted carbazoles, the oxidation is reversible and the potential is affected by the substituents. For 3,6-unprotected carbazoles, on the other hand, the oxidized forms can undergo dimerization. Their corresponding dimers have been independently synthesized by chemical methods and have exhibited identical spectral properties. The para position of the 9-phenyl group is relatively insensitive for redox and chemical reactions. The amino derivatives are unstable in carbazole cation radical form compared with their triphenylamine counterparts.
