Two novel donor-acceptor type monomers, ethyl 4-(3,6-di(thiophen-2-yl)-9H- carbazole-9-yl)-benzoate (ETCB) and 9-(4-nitrophenyl)-3,6-di(thiophen-2-yl)-9H- carbazole (NDTC), were synthesized and characterized. Both the monomers show good electrochemical ac

Three compounds with nitrocarbazole frameworks were synthesized and their electrochemical reversibility as organic electrocatalysts was studied by cyclic voltammetry. The electrochemical reversibility and oxidation-reduction potential of the compounds were greatly affected by their substituents. The oxidation-reduction potential of the compound with an electron-donating group was negative, while that of the compound with an electron-withdrawing group on the carbazole framework was positive. The electrocatalytic oxidation activities of the nitrocarbazole compounds were investigated through cyclic voltammetry and controlled potential electrolysis at room temperature. The electrocatalysts showed excellent selectivity for p-methoxybenzyl alcohol, converting it to the corresponding aldehyde through electro-oxidation with just 2.5 mol% of the electrocatalysts presented. The electrocatalysts maintained their excellent electroredox activity following recycling.

Two series of novel diamide- or diimide-cored N-phenylcarbazole dendrons were synthesized from condensation reactions of 3,6-di(carbazol-9-yl)-N-(4-aminophenyl)carbazole (NH2-3Cz) with aromatic dicarboxylic acids and tetracarboxylic dianhydrides, respectively. These dendrons can be electropolymerized into crosslinked poly(amide-carbazole) and poly(imide-carbazole) films on the electrode surface in an electrolyte solution via the coupling reactions between carbazole radical cations. Cyclic voltammograms of the electro-generated polymer films showed two reversible oxidation redox couples accompanied by a color change from the colorless neutral state to the yellow-green and blue oxidized forms in the range of 1.11-1.34 V. The electrochromic behavior of the film is clearly interpreted on the basis of spectroelectrochemical studies. Single layer electrochromic cells were also fabricated as preliminary evaluation for their application as electrochromic devices.
