  • Fused thiophene acenes and organic semiconductors made therefrom
    Patent number: 8021578
    Abstract: This invention relates to fused thiophene acene compounds and their use in organic semiconductors. The compounds exhibit useful electronic properties such as high mobility and high on/off ratio. The compounds can be used in electronic devices such as field effect transistors (FETs), display devices, light-emitting diodes, photovoltaic cells, photo-detectors, and memory cells. Also provided are methods for making the fused thiophene acenes.
