selective attachment of fluorescent dyes to the core-forming
block, we produced patchy micelles of diblock copolymers with fluorophores
localized in the micellar cores. From these patchy micelles functionalized
with dyes, fluorescent supracolloidal chains in a few micrometers
were polymerized by combining the patches in neighboring micelles,
indicating that selective modification of the core-forming block delivered
the functionality into the supracolloidal chain without altering the
polymerization of patchy micelles. Thus, with the same polymerization
condition, we were able to produce red-, green-, and blue-emitting
supracolloidal chains by varying the fluorescent dyes attached to
the core-forming block. In addition, we directly visualized individual
supracolloidal chains by fluorescence confocal microscopy as well
as by transmission electron microscopy.
