- a specification such as 2b:BisC1:TEG1 (45%:45%:10%) means that the material 2b accounts for 45% by volume, BisC1 for 45% and TEG1 for 10% in the layer present.
- the electron transport layer can also consist of a mixture of two materials.
- the electroluminescent devices are characterized in a standard way.
- the electroluminescence spectra, the current efficiency (SE, measured in cd/A) and the external quantum efficiency (EQE, measured in %) are determined as a function of the luminance, calculated from current-voltage-luminance characteristics assuming a Lambertian radiation characteristic, and the lifetime .
- the electroluminescence spectra are determined at a luminance of 1000 cd/m2 and the CIE 1931 x and y color coordinates are calculated from this.
- the specification U1000 in Table 18 describes the voltage required for a luminance of 1000 cd/m2.
- SE1000 and EQE1000 denote the current efficiency and external quantum efficiency, respectively, achieved at 1000cd/m2.
- the material combinations according to the invention can be used in the emission layer in phosphorescent OLEDs.
- the compounds 2b and 9b according to the invention are used as green matrix material in the emission layer in examples E1 to E2, and 10b and 18b are used as red matrix material in the emission layer in examples E16 to E17.
- the combinations according to the invention of compound BisC1 with corresponding compound b, 2b and 9b are used as matrix material in the emission layer in examples E3 to E5.
- Further combinations according to the invention of the compounds 24a and 2dB with the compounds Tz1 to Tz8 are used as matrix material in the emission layer in Examples E6 to E15.
- example E18 A further combination according to the invention of the compounds 18b with the compound BisC2 is used in example E18 as the red matrix material in the emission layer.
- compound 9b according to the invention is used as electron blocking material in the EBL.
- compound 28b according to the invention is used as hole transport material. Table 1: Structure of the electroluminescent devices
