  • 3,7-bis(2-oxoindolin-3-ylidene)benzo[1,2-b:4,5-b?]difuran-2,6-dione dicyanide-based materials and uses thereof in organic electronic devices
    Patent number: 11545633
    Abstract: The development of air-stable unipolar n-type semiconductors with good solubility in organic solvents at room temperature remains a critical issue in the field of organic electronics. Moreover, most of the existing semiconducting materials exhibit LUMO energy levels higher than ?4.0 eV, making electron transport sensitive to both moisture and oxygen. Bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof are disclosed herein. More specifically, bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof for use in organic electronics are disclosed. A process for the preparation of bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide and derivatives is also disclosed. The bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof are characterized by high electron mobilities and are suitable for use as n-type semiconductors in organic electronics.
    Type: Grant
