Abstract

The invention discloses a diarylamine compound and an organic electroluminescent device containing the same, belonging to the technical field of semiconductor materials. The structure of the compound is shown as a general formula (1). The middle of the diarylamine compound is bridged by an aromatic ring, a fluorenyl group is connected to an amido group, and the diarylamine compound has excellent hole transport capacity, membrane phase stability and weather resistance. When a hole transport material of the organic electroluminescent device is formed by using the novel arylamine-based compound, effects such as improved device effect, reduced driving voltage, and prolonged lifetime can be obtained.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, and more specifically relates to a novel bisarylamine compound and an organic electroluminescent device comprising the bisarylamine compound which is suitable for various display devices. Background technique [0002] The carriers (holes and electrons) in the organic electroluminescent device (OLED) are respectively injected into the device by the two electrodes of the device under the drive of the electric field, and meet in the organic light-emitting layer to recombine and emit light. High-performance organic electroluminescent devices require various organic functional materials to have good photoelectric properties. For example, as a charge transport material, good carrier mobility is required. The injection and transport characteristics of hole injection layer materials and hole transport layer materials used in existing organic electroluminescent devices are relatively weak,...
