摘要:The present inventive concept relates to an in situ core/shell perovskite nanocrystal film formed by an in situ nanocrystal synthesis process, a method for producing the same, and a light emitting device comprising the same as a light-emitting layer. The in situ core/shell perovskite nanocrystal film formed by the in situ nanocrystal synthesis process according to the present inventive concept exhibits a strong charge confinement effect by nanocrystal formation, and can simultaneously greatly improve the luminescence efficiency and lifetime by maintaining the fast charge transport capability of polycrystalline perovskite.

摘要:A high-purity organometallic iridium complex is provided. The organometallic iridium complex includes iridium and a plurality of ligands cyclometallated to the iridium. Each of the plurality of ligands includes a heteroaromatic ring having a coordinatable nitrogen atom. In LC analysis of the organometallic iridium complex, an impurity which has a monochlorinated ligand among the plurality of ligands is 0.1% or less by quantitating using peak area count with a PDA detector.

发明人：CHEN LIANG-JYI; WENG WEN-KUO; KU CHUN-NENG; LU PO-YEN
摘要:The present invention discloses a novel compound useful as the material for a red organic EL device. The novel compound is produced by connecting a benzene ring at the positions 2 and 3 of withdrawing group 2,5-dimethyl-4-(2,2-dicyano)pyrane, and connecting a conjugated donating group at position 5. Using this compound, the EL emission is shifted to the red spectral region, and a higher purity in color for red EL elements is obtained. The synthesis of the compound is easy and the product yield is improved compared to the prior art. Moreover, the red organic EL devices fabricated using the compound have properties that conform with existing NTSC standards.
