Abstract

The invention discloses an electron transport type heteroanthracene derivative, a preparation method and application thereof, and an organic electroluminescent device. The heteroanthracene derivativehas a parent nucleus structure of heteroanthracene, and is modified by a group to form a D-A type compound. The heteroanthracene derivative has remarkable and excellent fluorescence electroluminescentcharacteristics and electron transport characteristics, has relatively high quantum yield and electron mobility when being used as a luminescent object material, an electron transport material or a hole blocking material of an organic electroluminescent device, can effectively solve the problem of electron and hole imbalance in the device, emits purer light color, and compared with similar compounds and compounds in the prior art, has more remarkable advantages in starting voltage, current efficiency, service life and thermal stability.

Description

technical field [0001] The invention relates to the field of photoelectric materials, in particular, the invention relates to an electron-transporting xanthene derivative and an organic electroluminescence device thereof. Background technique [0002] OLED stands for Organic Light Emitting Diode, also known as Organic Laser Display. OLED has the characteristics of self-illumination. It uses a very thin organic material coating and glass substrate. When the current passes through, the organic material will emit light, and the OLED display screen has a large viewing angle and can significantly save power. Therefore, OLED is regarded as One of the most promising products of the 21st century. However, so far, OLED devices have not been widely used, and the efficiency of the device is an important reason for restricting their popularization. [0003] In OLED devices, the design and combination of the light-emitting layer play a key role in the performance of the device, which d...
