Preparation of Organic-Inorganic Hybrid Nanocomposites via Pd-Catalyzed Amination of Dibromobenzene with Octa(aminophenyl)silsesquioxane

Abstract

Novel organic-inorganic hybrid nanocomposites have been obtained by the condensation polymerization of dibromoarene with Octa(aminophenyl)silsesquioxane via palladium-catalyzed aryl amination reaction. The structures of polymers are characterized by means of FT-IR, solid ¹³C, and ²⁹Si NMR spectroscopy; the results show an agreement with the proposed structure, and the POSS building block was successfully weaved in the structure without obvious alteration of the characteristics and structure. TGA results show that polymers possess good thermal stability.
