Abstract

The invention provides a compound having the structure as follows, wherein the substituent groups R1 and R2 are both electron withdrawing groups. The invention also provides a material and an organic light-emitting device which include the compound. The organic light-emitting device has low driving voltage, high efficiency and good color coordinates and is more high-effective and energy-saving.

Description

technical field [0001] The present invention relates to a compound, in particular a compound that can be used for preparing organic electroluminescent devices. Background technique [0002] At present, the display is mainly based on TFT-LCD (thin film transistor type liquid crystal display), because the display is a non-self-luminous display, it must project light through the backlight, and sequentially penetrate the polarizer and glass in the TFT-LCD panel. Substrates, liquid crystal layers, color filters, glass substrates, polarizers and other related components, and finally enter the human eye for imaging to achieve the function of display. However, its display screen has shortcomings such as slow response rate, power consumption, and narrow viewing angle, which are insufficient to become a perfect display screen. [0003] With the development of the information age, organic electroluminescent devices (OLEDs) with high efficiency, energy saving and light weight have attr...
