Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of organic electroluminescence, and in particular to an organic light-emitting device. Background Art
[0002] Organic light-emitting diodes (OLEDs) have attracted significant attention due to their wide viewing angles, excellent contrast, fast response speed, high brightness, low drive voltage, and flexibility. Currently, OLED displays are widely used in display panels for mobile phones, tablets, televisions, and automotive applications.
[0003] OLED devices are generally classified as bottom-emitting or top-emitting, differing in the direction of light emission from the device. In bottom-emitting devices, light generated by the radiative recombination process is emitted toward the device's base substrate, while in top-emitting devices, light is emitted away from the base substrate. Therefore, in bottom-emitting devices, the electrode closest to the base substrate is generally transparent or semi-transparent, while in top-emitting devices, the electrode away from the base substrate is often transparent or semi-transparent, thereby reducing light attenuation. Depending on the specific device structure, either the anode or cathode can serve as the transmissive electrode in both top-emitting and bottom-emitting devices.
[0004] Materials commonly used to form transmissive electrodes include transparent conductive oxides (TCOs), such as indium tin oxide (ITO) and zinc oxide (ZnO), or thin films, such as thin films formed by depositing thin layers of silver (Ag), aluminum (Al), or various metal alloys, such as magnesium silver (Mg:Ag) alloy and ytterbium silver (Yb:Ag) alloy, with a composition volume ratio of about 1:9 to about 9:1. Multilayer electrodes including two or more layers of TCO and / or metal films can also be used. Thin films of up to about tens of nanometers help to improve electrode transparency and provide the electrode with good optical properties (for example, reducing the microcavity effect). However, the reduction in the thickness of the transmissive electrode is accompanied by an increase in the sheet resistance, which will cause the device to produce a larger current-resistance (IR) drop, thereby affecting the device's luminous efficiency and performance.
[0005] To reduce the impact of IR drop on devices, an auxiliary electrode is typically introduced into the device. This can be achieved by depositing a conductive coating that is electrically connected to the transmissive electrode of the OLED device. A nucleation inhibition layer is also typically introduced to inhibit metal deposition on the surface of the thin layer, thereby ensuring that the conductive coating is primarily deposited in other areas of the device. However, the nucleation inhibition layers currently used in most devices are not ideal for inhibiting metal deposition on the surface of the thin layer. Therefore, the development of organic light-emitting devices with a nucleation inhibition layer that performs well is essential. Summary of the Invention
[0006] In response to the problems existing in the prior art, the present invention provides an organic light-emitting device and a heterocyclic compound used in a nucleation inhibition layer thereof, which suppresses the deposition of metal on the surface of the thin layer by improving the nucleation inhibition layer, thereby effectively improving the device performance.
[0007] The present invention provides an organic light-emitting device, comprising a substrate, an anode disposed on the substrate, an organic layer disposed on the anode, a cathode disposed on the organic layer, and a nucleation inhibition layer disposed on a side of the cathode facing away from or close to the anode, wherein the nucleation inhibition layer comprises a heterocyclic compound represented by Formula 1.

[0330] Determination of transmittance
[0331] In the present invention, the glass substrate is ultrasonically cleaned twice with a 5% glass cleaning solution for 20 minutes each time, then ultrasonically cleaned twice with deionized water for 10 minutes each time. It is then ultrasonically cleaned for 20 minutes each in acetone and isopropyl alcohol, followed by drying at 120°C. All organic materials are sublimated to a purity of over 99.99%.
[0332] In calculating optical transmittance measurements, any loss or absorption of light due to the presence of the glass substrate and nucleation inhibiting coating is subtracted from the measured transmittance (taken at a wavelength of approximately 550 nm).
[0333] Optical transmittance test instrument: UV-visible spectrophotometer (manufacturer: Shanghai Xipu Instrument Co., Ltd., model: UV-2202PC)
[0334] Example 1: Preparation of Sample 1
[0335] A series of samples were made by depositing a nucleation inhibition layer of Compound 1 about 20 nm thick on a glass substrate. The surface of the nucleation inhibition coating was then subjected to an open mask deposition of magnesium. Each sample was subjected to an average evaporation rate of about The magnesium vapor flux was 200 s. When depositing the magnesium coating, a deposition time of about 200 seconds was used to obtain a reference magnesium layer thickness of about 50 nm. Optical transmittance measurements were then used to determine the relative amount of magnesium deposited on the nucleation-inhibiting coating surface.

[0342]
[0343]
[0344] It can be seen from the results in Table 2 that compared with Comparative Examples 1 to 5, Examples 1 to 43 have higher optical transmittance. This is because when the structure of Formula 1 described in the present invention is applied to the nucleation inhibition layer, it can effectively inhibit the deposition of metal on its surface. Therefore, when the nucleation inhibition layer containing the structure of Formula 1 is applied to the organic electroluminescent device, the device performance can be effectively improved.

However, without departing from the principles of the present invention, a person skilled in the art may make various improvements in form or detail to the present invention, and these improvements also fall within the scope of protection of the present invention.
