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

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.
