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.
