End-on Chain Orientation of Poly(3-hexylthiophene)-Based Diblock Copolymers via Controlled Regioregularity-Induced Microphase Separation |
| 초록 |
We synthesized amphiphilic poly(3-hexylthiophene)-block-poly(3-(2-methoxyethoxy)methylthiophene) copolymer (P3HT-b-P3MEGT) with controlled regioregularity (RR) of P3HT. As the RR decreased, the crystallinity of the P3HT decreased and the microphase separation prevailed over the crystallization effect. P3HT-b-P3MEGT with RR of P3HT having 83% showed well-ordered lamellar nanostructures. P3HT-b-P3MEGT thin films showed parallel oriented lamellar nanostructures to the substrate due to a large difference of surface tension. Parallel oriented lamellar nanostructure induced end-on orientation of P3HT and P3MEGT chains, which enhances significantly the vertical hole mobility more than 50 times compared to P3HT continuous thin films with edge-on orientation. |
