Abstract
A well‐defined amphiphilic block copolymer bearing a reactive azide group at the interface of two blocks, poly(ethylene oxide)(‐azido)‐block‐polystyrene (PEO(‐N~3~)‐b‐PS), has been successfully synthesized via a combination of end group transformation and atom transfer radical polymerization (ATRP). The subsequent [3 + 2] cycloaddition reaction between PEO(‐N~3~)‐b‐PS and C~60~ led to the facile preparation of PEO(‐C~60~)‐b‐PS, in which a single C~60~ moiety was located at the diblock junction point. Fullerene‐containing hybrid vesicles were then fabricated for the first time via the supramolecular self‐assembly of PEO~45~(‐C~60~)‐b‐PS~380~ in aqueous solution using 1,4‐dioxane as the cosolvent. The current example augurs well for tunable spatial ordering of desired moieties (fullerene or other functional nanoparticles) by employing block copolymers as self‐organizing templates.
