The Study of Self-assembly Structure of Poly(3-hexylthiophene) Regio-Block Copolymers and their Structure-Property Relationship |
| 초록 |
Poly(3-hexylthiophene) (P3HT) has received a great deal of attention in organic electronic application for their controllable morphology and high conductivity. Here, we demonstrate regioregularity-controlled P3HT copolymer with regioregular-regiorandom block that show high electrical and mechanical properties. We synthesized the series of P3HT copolymers by combination of crystallizable regioregular block with identical molecular weight and amorphous regiorandom block with varying molecular weight, using living characteristics of GRIM polymerization. Then, we produced well-defined nanowires film using a solution self-assembly to construct highly ordered electron channel. We observed the small amount of regiorandom block facilitated the formation of longer nanowire, while too lengthy regiorandom block hindered the growth of assembly. This was attributed to the length-dependent charge carrier mobility, where the hole mobility was improved with higher degree of order. |
