Performances of SC-OFETs based on β-MT-acenedithiophenes and rubrenea.
| Compound | Mobility (cm2 V−1 s−1) | V th (V) | On/off ratio |
|---|---|---|---|
| β-MT-BDT | 0.22 (0.38) | −21.5 | 105 to 106 |
| β-MT-NDT | 0.25 (0.35) | −11.8 | 105 to 106 |
| β-MT-ADT | 3.44 (4.08) | −4.5 | 104 to 106 |
| Rubrene | 3.79 (4.73) | −5.1 | 106 to 107 |

The charge transport directions in the SC-OFETs are along the π-stacking directions (crystallographic b-axis for rubrene and c-axis for β-MT-acenedithiophenes, Fig. S7). The mobilities were extracted from the saturation regime of the transfer curves. The average mobilities and Vths are based on more than 10 devices, and values within parentheses are the highest mobilities.
