Mesoporous Organic–Inorganic Hybrid Materials Built Using Polyhedral Oligomeric Silsesquioxane Blocks

Rounding up the POSSe: Polyhedral oligomeric silsesquioxanes (POSS), one of the smallest hybrid nano building blocks, were weaved into multifunctional hierarchical mesoporous hybrid materials. The mesoporous organic–inorganic hybrid material was synthesized by coassembly and condensation of the POSS compound around the block copolymer P123 micelles and subsequent release of the porogen (see scheme), resulting in a uniform pore size of 4.40 nm.
