This research characterizes mainly on 3, 6 and 9-position substituent of carbazoles. In this research, the oxidation is irreversible when 3, 6-position don』t have any substituent, on the other hand, there is a redox couple at about E1/2= +1.23 V when that have substituent. It also can prove by spectroelectrochemistry, when we oxidize the compound and will produce a dimer carbazole. The second part the first part of research, the dendrimer derivatives of carbazole, and observe the substitueut effect in electrochemistry. In cyclic voltammetry, we can find two redox couples in oxidative more negatively, electro-withdrawing groups will make potential more positively. In spectroelectrochemistry, the characterization of cation radical has a broad band in near-IR region. By the spectroeletrochemistry studies, we can get different spectrum when we applied the different potential.
