![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](/abs-image/US/2023/01/03/US11545633B2/abs.jpg.150x150.jpg)
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.
