Chemical oxidation of α,ω-bis(N-carbazolyl)alkanes by FeCl3 in the presence of N-(ω-functional alkyl)carbazoles allowed the obtention of telechelic stairs-shaped poly(bicarbazyl-alkylene)s bearing terminal groups such as halogens, nitrile, carboxylic acid. High molar masses materials were obtained exhibiting a particularly good solubility in organic solvents due to their special architecture. Electrochemical studies disclosed that redox polymers were obtained displaying a remarkable colourlessgreenblue electrochromism. Furthermore materials could be used as a blue lightemitting layer into diodes.
