Description

technical field

[0001] The present invention relates to a compound and an organic light emitting diode comprising it, in particular to an aromatic compound and an organic light emitting diode comprising it. Background technique

[0002] Organic light-emitting diode (OLED) flat-panel displays have advantages such as wider viewing angles, faster response time, and thinner volume than liquid crystal displays, and are currently being used in large-area, high-brightness, and full-color displays.

[0003] In order to develop a full-color flat-panel display, developing stable and high-efficiency light-emitting materials (red, green, blue) is the main goal of current OLED research. However, compared with red luminescent materials and green luminescent materials, the development of blue luminescent materials in terms of luminous efficiency and luminous lifetime is relatively slow, so the development of novel blue luminescent materials with high luminous efficiency and long life is cu...
