Electroactive multifunctional telechelic stairs-shaped poly(bicarbazyl-alkylene)s

Chemical oxidation of alpha,omega-bis(N-carbazolyl)alkanes by FeCl3 in the presence of N-(omega-functional alkyl)carbazoles allowed the obtention of t elechelic stairs-shaped poly(bicarbazyl-alkylene)s bearing terminal groups such as halogens, nitrile, carboxylic acid. High molar masses materials wer e obtained exhibiting a particularly good solubility in organic solvents du e to their special architecture. Electrochemical studies disclosed that red ox polymers were obtained displaying a remarkable colourless<->green<->blue electrochromism. Furthermore materials could be used as a blue light-emitt ing layer into diodes.
