Organic thin-film transistors (OTFTs) have shown great potential in various electronic applications, such as the development of low-cost, light-weight, large-area, and flexible panels/circuits. Currently, the best values of the field-effect mobility of OTFT devices based on vacuum-deposited polycrystalline small molecules are in the range of a few cm2 V-1 s-1. Fullerene C60 is a well-known n-type semiconductor with good electron-accepting and electron-transporting properties. Ever since the commercial availability of synthetically useful amounts of C60 and higher fullerenes (C70, C78 and C84) much work has been done to investigate the physical properties and the reactivity for the applications such as solar cells, thin film transistors (TFT), memory and sensing devices. Here we report new C60 derivatives containing alkylated thiophene units, which can be utilized for OTFTs based on solution-processing technique. |
