“…Among fully functionalized POSSs such as T 8 , T 10 , or T 12 containing 8, 10, or 12 silicon atoms, respectively, most interest has been focused on cubic spherosilicates (hexahedral octafunctionalized silsesquioxanes, T 8 ). [2][3][4] Their attractiveness derives from the fact that they are highly soluble in common organic solvents making them useful compounds for the construction of numerous well-defined hybrid materials. Such compounds can effectively anchor various reactive substituents, R, to the siloxane core and, in fact, the structural and physicochemical properties as well as the potential applications of the POSSs are directly related to the precisely designed side chains.…”
