Abstract

The present invention relates to the field of organic electroluminescence, and can provide an organic compound represented by a general formula (1). The present invention also provides an organic electroluminescent element produced by using the compound as a hole transport material.

Description

technical field [0001] The invention relates to the field of organic electroluminescent materials, in particular to a novel compound material with a combination of fluorenyl and 2,4-diphenylaniline as a central skeleton, and its application in OLED device structures. Background technique [0002] OLED (Organic light-Emitting diode) display technology has the advantages of self-illumination, high contrast, fast response speed, and high color saturation. In particular, it does not contain a backlight, the device structure is simple, and the operating temperature range is wide. The characteristics of preparing flexible display make it the next generation display technology after LCD, and it has gradually shown its broad prospects for commercial application. [0003] Generally, the simplest OLED device structure is to vapor-deposit an organic light-emitting material with a thickness of tens to hundreds of nanometers between two electrodes, and to make the material emit light by ...
