Water-repellent: Fluorinated polyhedral oligomeric silsesquioxanes (POSS) are produced by facile, single-step, base-catalyzed condensation of trialkoxy silanes. The octameric fluorinated polyhedra are soluble, thermally stable, and hydrophobic, exhibiting static water contact angles up to 154°. The fluorodecyl POSS is believed to be the most hydrophobic crystalline solid known.
