    摘要: A method of forming an organic layer for an organic electronic device (e.g., an OLED) by using a liquid composition comprising a small molecule organic semiconductor material mixed in a solvent preparation in which the content of higher boiling impurities is reduced. The solvent preparation comprises a high boiling point solvent and 0.1 wt % or less of impurities having a higher boiling point than the solvent. The liquid composition is deposited on a surface by inkjet printing to form the organic layer. Also, provided are liquid compositions which can be used to make organic layers.

    摘要: A liquid composition (e.g., inkjet fluid) for forming an organic layer of an organic electronic device (e.g., an OLED). The liquid composition comprises a small molecule organic semiconductor material mixed in an aromatic solvent. The aromatic solvent, when left as a residue in the organic layer, is capable of presenting relatively reduced resistivity to charge transport or facilitating charge transport in the organic layer that is deposited, as compared to other conventional solvents. In certain embodiments, the aromatic solvent compound has the following formula: wherein R represents one or more optional substituents on the benzene ring, wherein each R is independently an aliphatic group containing from 1-15 carbon atoms; and wherein X is a substitution group that contains an electron-withdrawing group selected from nitrile, sulfonyl, or trifluoromethyl.

    摘要: A light emitting diode (LED) formed by depositing an LED chip and coupling a stability layer to the LED chip. Semiconductor nanocrystals are placed in a first matrix material to form a nanocrystal complex layer. The nanocrystal complex layer is deposited on top of the stability layer. A thickness of the stability layer is chosen to maximizes a power of a light output by the nanocrystal complex layer. The matrix material and the stability layer can be of the same type of material. Additional layers of matrix material can be deposited on top of the nanocrystal complex layer. These additional layers can comprise matrix material only or can comprise matrix material and semiconductor nanocrystals to form another nanocrystal complex layer.
