Abstract

Junction-functionalized block copolymers can be used in forming nanostructures. A junction-functionalized block copolymer can include a first polymer block joined to a second polymer block by a junction, where the junction includes one or more electrostatically charged moieties. The block copolymer can include a moiety of formula (I):A-J-B  (I)where A is a first polymer block, B is a second polymer block, where the A block and the B block are chemically dissimilar, and J is a junction linking the A block to the B block, and including one or more electrostatically charged moieties.
