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)-block-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.
成功地从二嵌段共聚物聚(3-己基噻吩)-嵌段-聚苯乙烯制备了长度可达约 700nm 的具有单晶态π共轭聚噻吩核的单分散纤维状胶束，使用一维自种晶技术。向所得纳米纤维中添加具有不同冠形成嵌段的聚噻吩嵌段共聚物，通过结晶驱动的种晶生长形成分段的 B-A-B 三嵌段共胶束。这些进展的关键似乎是在自种晶条件下形成相对无缺陷的单晶态胶束核。
