Abstract

Polyhedral oligomeric silsesquioxane functionalized with imidazolium chloride peripheries IJPOSS-Imi) wassuccessfully synthesized through a novel synthesis protocol. The solid was extensively characterized via 1HNMR, 13C NMR and IR spectroscopy as well as combustion chemical analysis, mass spectrometry and transmission electron microscopy. Moreover, an in-depth investigation through 29Si NMR was performed.POSS-Imi was used for the first time as a catalyst for the conversion of CO2 and epoxides into cyclic carbonates with excellent results in terms of both yield and selectivity. The catalyst displayed improved catalytic performance with respect to unsupported 1-butyl-3-methylimidazolium chloride. The enhanced activity was ascribed to the proximity effect generated by the increased local concentration of imidazoliumspecies surrounding the inorganic silsesquioxane core.
