Molecular self‐attack: According to mythology, a scorpion may sting itself to death; similarly, 3‐aminopropyltriethoxysilane catalyzes its own hydrolysis in the atomic layer deposition (ALD) of SiO 2 thin films and nanostructures. Between 120 and 200 °C, the growth rate is constant at 0.06 nm per ALD cycle. The SiO 2 films are chemically and optically pure. SiO 2 nanotubes of aspect ratio 500 exhibit smooth walls of accurately controlled thickness.
