Highly ordered gold nanotubes using thiols at a cleavable block copolymer interface

J Am Chem Soc. 2009 Jul 29;131(29):9870-1. doi: 10.1021/ja902567p.

Abstract

We have prepared functionalized nanoporous thin films from a polystyrene-block-polyethylene oxide block copolymer, which was made cleavable due to the intervening disulfide bond. The cleavage reaction of the disulfide bond leaves behind free thiol groups inside the nanopores of polystyrene thin film. This nanoporous thin film can be used as a template for generating gold nanoring structures. This strategy can provide a facile method to form a highly ordered array of biopolymer or metal-polymer composite structures.
