Abstract

The invention discloses an arylamine carbazole compound and an organic electroluminescent device containing the same, and belongs to the technical field of semiconductor materials, and the structure of the compound is shown as a general formula (1). The arylamine carbazole compound provided by the invention is bridged by an aromatic ring, and carbazole and arylamine are dispersedly connected to the aromatic ring, so that the arylamine carbazole compound has excellent hole transport capacity, membrane phase stability and weather resistance. When a hole transport material of an organic electroluminescent device is formed by using the novel arylamine carbazole compound, the performance of the device can be improved, for example, the efficiency of the device is improved, the driving voltage is reduced, and the service life is prolonged.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, and in particular, to a novel arylamine carbazole compound, and an organic electroluminescence device comprising the arylamine carbazole compound suitable for various display devices. Background technique [0002] Carriers (holes and electrons) in an organic electroluminescent device (OLED) are injected into the device by the two electrodes of the device, respectively, driven by an 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 with good optoelectronic properties. For example, as a charge transport material, it is required to have good carrier mobility. The hole injection layer materials and hole transport layer materials used in the existing organic electroluminescent devices have relatively weak injection and transport properties, and the ho...
