OLED Materials

关于

Organic light-emitting diodes (OLEDs) consist of layers of organic materials with charge transport or emissive properties sandwiched between conductive electrodes. OLEDs emit light at a specific color and wavelength, depending on the combination of organic material components. By selecting appropriate host and dopant OLED materials, the emission can be tailored to achieve desired results. An OLED device has a multilayered system: Anode | Hole Injection Layer | Hole Transport Layer | Light Emitting Layer | Electron Transport Layer | Electron Injection Layer | Cathode Thermally activated delayed fluorescent (TADF) materials along with fluorescent and phosphorescent molecules are the three main groups of compounds found in the light-emitting host layer. Emerging fourth-generation materials, such as multi-resonance thermally activated delayed fluorescent (MR-TADF) compounds, are also being explored. Each group of host material has a distinct photoluminescent mechanism, which can be strategically utilized in device architectures. As OLEDs become more widely used commercially, device efficiency is crucial. One approach is through selecting the appropriate charge transport layer materials with well matched HOMO and LUMO energy levels to the anode and cathode. Additionally, incorporating electron and hole injection layers can significantly enhance the work function and reduce the energy barrier for charge transport at the electrodes. We offer high-purity OLED materials, including fluorescent, phosphorescent, and TADF host materials, as well as a range of compatible dopant materials and charge transport layer materials, such as electron and hole-injecting materials.
