- Abstract
Dual functionalization of nanostructures of block copolymers by simultaneous incorporation of two functionalities into the nanostructures is demonstrated. For this purpose, a blending strategy of two block copolymers is employed, which have the same basic chemical structure for each block but differ in small amounts of functional moieties in one of the blocks. Block copolymers containing thiol and fluorophore functionalities are synthesized, utilizing a block copolymer that features a reactive block of activated esters. With thiol-functionalized block copolymers, selective incorporation of quantum dots (QDs) to lamellar nanostructures is first validated by transmission electron microscopy. Fluorophore functionalization of lamellar nanostructures is also confirmed with fluorophore-anchored block copolymers by photoluminescence spectroscopy. Then, with a blending strategy of two functionalized block copolymers, dual functionalization of lamellar nanostructures of block copolymers is induced by simultaneous incorporation of QDs and organic fluorophores, which exhibit fluorescence resonance energy transfer due to nanoscale confinement.
