Abstract

n selective solvent, diblock copolymers self-associate into spherical micelles consisting of soluble coronas and insoluble cores. In principle, the presence of chemically distinct domains such as core and corona can facilitate the selective placement of functionalities in different region. Many functional materials such as inorganic nanoparticles(NPs), fluorescent dyes, and therapeutic agents have been selectively localized in the core, interface, or corona of micelles by adjusting their chemical affinity with each block. From this feature of copolymer micelles, we envisioned that two different kinds of metal NPs can be simultaneously positioned harvested by plasmonic function can be utilized by the catalytic sites. To testify this hypothesis, catalytic reduction of 4-nitrophenol by NaBH4 was selected to evaluate dual functions of micellar assemblies in chemical reaction.
