Description

Technical field: [0001] The present invention relates to a novel composition, including Sulfolane or Dimethylsulfone, and at least one organic functional material, and its application in organic electronic devices, especially light-emitting devices, and organic Methods of production of electronic devices and their applications in lighting and display technology and elsewhere. Background technique: [0002] Organic light-emitting devices, especially organic light-emitting diodes (OLEDs) (see TANG et al. Appl. Waiting to become the most promising next-generation display and lighting technology. In particular, they may form films from solutions by printing methods, such as inkjet printing (InkJet Printing), screen printing (Screen Printing) and other technologies, which can greatly reduce manufacturing costs, so it is especially suitable for large-screen displays and illuminators. is attractive. [0003] OLEDs based on small molecules have excellent performance and have reac...
