Mono-chlorination Strategy on Isoindigo-based Conjugated Polymers for N-type Organic Field-effect Transistors |
| 초록 |
Although the comprehensive studies of conjugated polymer for organic field-effect transistors (OFETs), n-type OFETs still suffer from lags in development. In this regard, introducing chlorine atom has emerged as an effective strategy for enhancing n-type properties. Chlorination has advantages with short synthesis steps and empty 3d orbitals that can accept π-electrons. However, the issue of backbone distortion by the large size of the chlorine atom are remained to be addressed. To overcome the above-mentioned issue, mono-chlorinated isoindigo-based polymers, P1CIID-2T and P1CIID-DTBT were designed and synthesized. Mono-chlorinated polymers possessed higher planar backbone than that of the di-chlorinated one, resulting in increased crystallinity. Meanwhile, the LUMO energy levels were deep enough for efficient electron-transporting. OFETs were fabricated with synthesized polymers as active layer, then exhibited n-type characteristics with the highest electron mobility of 0.216 cm2/Vs. |
