Abstract: Conjugated aromatic azomethines containing a carbazole group were synthesized.Their structures have been confirmed by IR, MS and UV spectrometries.When iodine was used as the dope to the conjugated compounds, the electrical conductivities (EC) of the doped conjugated compounds were increased by several orders of magnitude.The thermal stability of these two compounds investigated by TGA shows a good result, which guarantees the correct result of EC when the compounds are heated.As can be seen from the CV characterization of the electrochemical properties .of these two compounds, the azomethine diamine and p-aminophenyl-9-ethylcarbazolyl azomethine possess electrochemical activity, which arises from the heteroatom of molecules.
