Structural design of poly(3-hexylthiophene) based graft copolymers to control their self-assembly behaviors in the solution |
| 초록 |
To achieve various and beneficial structures of rod-coil copolymer nanowires(NWs), designing the second corona block is of great important. Herein, we investigate the effect of architectural design of corona blocks on the NW formation by using conjugated polymer based graft copolymers. A series of poly(3-hexylthiophene)-graft-poly(2-vinylpyridine) (P3HT-g-P2VP) copolymer was prepared with two controlled parameters: grafting fraction (fg) and molecular weight of P2VP (Mn,P2VP). Grafting P2VP chains to P3HT backbones gave rise to steric hindrance and stretching penalty during crystallization, leading to the distinctive structure of NWs from the case of diblock copolymers, in which their lengths and curvatures were regulated depending on fg and Mn, P2VP as evidenced by careful characterization with DSC, UV-vis absorption, and TEM. Therefore, we demonstrate graft architectures of the P3HT based copolymers can provide a promising tailorbility in the solution–assembled nanostructures. |
