We report the preparation of a series of fiber-like micelles of narrow length distribution with an oligo( p -phenylenevinylene) (OPV)-core and a poly( N -isopropylacrylamide) (PNIPAM) corona via two different crystallization-driven self-assembly (CDSA) strategies. The average length L n of these micelles can be varied up to 870 nm by varying the temperature in self-seeding experiments. In addition, seeded growth was employed not only to prepare uniform micelles of controlled length, but also to form fiber-like A-B-A triblock comicelles with an OPV-core.
