Synthesis and characterization of conjugated polymers with semi-fluorinated alkyl chains: Enhanced transistor performance by self-organization and realization of multilayer architecture and orthogonal patterning |
| 초록 |
The fluorinated alkyl chains have weak intermolecular interactions owing to a symmetric distribution of charges, and lead to self-organization of fluorinated alkyl chains. The self-organization of fluorinated alkyl chains can lead to a more tightly packed conformation of conjugated polymer backbone. Especially, the highly ordered molecular crystal of conjugated polymers is considered to induce efficient charge transport. OFETs using novel conjugated polymers with fluorinated alkyls exhibited about two times higher effective mobility (up to 1.8 cm2/Vs) compared to those of hydrocarbon alkyl chains substituted polymers. In this presentation, we describe synthesis and characterization of a novel poly(semifluorododecyl-thiophene) derivatives composed of a semifluorinated alkyl chains and thiophene moieties to realize its full advantages. Furthermore, we demonstrated the bilayer ambipolar transistor and integrated circuit using orthogonal patterning of fluorinated polymer. |
