Uniform, High Aspect Ratio Fiber-like Micelles and Block Co-micelles with a Crystalline π‑Conjugated Polythiophene Core by Self-Seeding
Monodisperse fiber-like micelles
with a crystalline π-conjugated
polythiophene core with lengths up to ca. 700 nm were successfully
prepared from the diblock copolymer poly(3-hexylthiophene)-<i>block</i>-polystyrene using a one-dimensional self-seeding
technique. Addition of a polythiophene block copolymer
with a different corona-forming block to the resulting nanofibers
led to the formation of segmented B-A-B triblock co-micelles by crystallization-driven
seeded growth. The key to these advances appears to be the formation
of a relatively defect-free crystalline micelle core under the self-seeding
conditions
