  • Solution-processable electron-transport materials and related organic optoelectronic devices
    Patent number: 9172049
    Abstract: Charge transport compounds are provided. The compounds are useful in optoelectronic devices that include the compounds incorporated as a charge-transport layer. Methods for forming films of the compounds are also provided. Additionally, methods are provided for forming films of a charge-transport layer on an active layer of an optoelectronic device. The films are formed from a solution with solubility orthogonal to the solubility of the active layer, such that the active layer is not solvated during deposition of the charge-transport layer.
