技術說明

本發明是有關於一種含硼化合物、有機發光二極體的發光層以及有機發光二極體裝置，且特別是有關於一種可作為有機發光二極體發光層之摻雜物的含硼化合物、包含此含硼化合物的有機發光二極體的發光層以及有機發光二極體裝置。熱激活延遲螢光材料是繼螢光材料與磷光材料之後發展出的第三代有機發光材料。依據本發明目的，是提供一種含硼化合物，藉由其分子結構，使其具有熱激活延遲螢光材料特性，而有利於作為有機發光二極體發光層的摻雜物，其可使有機發光二極體裝置具有高效率、低成本並可提供寬廣的光調色能力等優點。 The present disclosure relates to a boron-containing compound, an emitting layer of an organic light emitting diode and an OLED device. The present disclosure relates to a boron-containing compound which can be used as a dopant of an emitting layer of an OLED, and an emitting layer of an OLED and an OLED device having the same. TADF materials are the third generation organic light emitting materials, which are developed after the fluorescence materials and the phosphorescence materials. To sum up, how to improve the molecular structure of the boron-containing compounds, in which the electron donating groups and the electron accepting groups are properly arranged so as to feature the boron-containing compounds with TADF properties, and accordingly can break through the impediment in the application of the organic light emitting materials and provide the OLEDs with excellent efficiency, is the goal of the relevant industry and academia.
