Problems solved by technology

In addition, for the collocation of OLED devices with different structures, the photoelectric functional materials used have strong selectivity, and the performance of the same material in devices with different structures may be completely different.
[0008] At present, the research of fluorescent materials has made great progress and can meet the needs of industrialization; however, there are still deficiencies in its efficiency and lifespan, and it is difficult to meet the requirements of full-color RGB
The main reason is the lack of efficient and stable host materials; especially for improving device life, the stability of host materials is particularly important

Abstract

The invention discloses an organic light emitting compound material and application of the organic light emitting compound material. The structural formula of the compound material is as shown in the general formula (1). The material can form an amorphous thin film easily, is high in heat stability and high in singlet state energy level, and is therefore can be used as a main material of a light emitting layer in an organic light-emitting device.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to the synthesis of a fluorescent compound and its application in an organic light-emitting diode as a host material of a light-emitting layer. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. [0003] Currently, OLED display technology has been applied in smart phones, tablet computers and other fields, and will further expand to large-size applications such as TVs. However, compared with the actual product application requirements, the luminous efficiency and service life of OLED devices need to be further improved. [0004] The OLED light-emitting device is like a sandwich structure, i...
