Abstract

Polyhedral oligomeric silsesquioxane having carbazole moiety, octakis[2-(carbazol-9-yl)ethyldimethylsiloxy]silsesquioxane (POSS-Cz), was synthesized by hydrosilylation reaction between octakis(dimethylsiloxy)silsesquioxane and 9-vinylcarbazole in the presence of platinum catalyst, and can be characterized by ¹H, ¹³C, ²⁹Si NMR, IR, and MALDI-TOF MS spectroscopies. POSS-Cz is soluble in common organic solvents. Comparison of thermal, electrochemical, and optical properties of POSS-Cz with those of 9-ethylcarbazole (EtCz) and poly(9-vinylcarbazole) (PVCz) revealed that electrochemical and optical properties of POSS-Cz are similar to those of EtCz, but POSS-Cz shows glassy state similarly to PVCz.
