Design and Synthesis of Functional Silsesquioxane-Based Hybrids by Hydrolytic Condensation of Bulky Triethoxysilanes
Figure 7
Synthetic routes for cationic silsesquioxane hybrids by (a) hydrolytic condensation of a functionalized precursor derived from 2-(dimethylamino)ethyl acrylate (DMAEA), followed by quaternization, and (b) hydrolytic cocondensation of tetraethoxysilane (TEOS) with the DMAEA-based triethoxysilane precursor.
