• The formation of transient <I>N</I>-vinylcarbazole cation-radical and pyromellitic dianhydride anion-radical was demonstrated for the <I>N</I>-vinylcarbazole-pyromellitic dianhydride-solvent system by means of flash spectroscopy. The transient decay process was found to be solvent-dependent. In 1,2-dichloroethane the decay of the anion-radical was of the first-order at initial stage (<I>t</I><100 μs), and the second-order kinetics (<I>t</I><100 μs) then followed. In acetonitrile the transient decay followed the second-order kinetics in the whole time region.
