Stereoselective synthesis and luminescence properties of novel trans-regular N-alkylcarbazolylene–silylene–vinylene polymers

•Stereoregular carbazole oligomers have been synthesized via silylative coupling reaction.•Spectroscopic and photophysical properties of oligomer were characterized.•The length of the polymer does not change their photophysical properties.

Novel trans-stereoregular silylene–carbazolylene–vinylene derivatives (13–15) were synthesized via silylative coupling reaction of 3,6-bis(dimethylvinylsilyl)-N-alkylcarbazole (7–9) catalyzed by ruthenium–hydride complex RuHCl(CO)(PCy3)2 (1). All products were isolated, fully characterized by spectroscopic methods and GPC analyses and their absorption and fluorescence properties were determined.
