Growth of Silicon Oxide in Thin Film Block Copolymer Scaffolds

Thin films of asymmetric diblock copolymers have been used as scaffolds to define an ordered array of nanometer‐scale reaction vessels in which high density arrays of silicon oxide nanostructures (see Figure) are produced by exposure to silicon tetrachloride. Such site‐specific silicon oxide nanostructures could have widespread uses for sensory and optoelectronic applications.
