Embodiment 1

[0048] Preparation of Compound 1

[0049]

[0050] Preparation of Compound 1

[0051] To 1-1 (43.52 g, 100 mmol) and a solution of 1-2 (32.10 g, 100 mmol) in degassed toluene (500 mL), and the mixture was heated at reflux for 2 hours. The reaction mixture was cooled to room temperature, diluted with toluene and filtered through celite. The filtrate was diluted with water and extracted with toluene, and the combined organic phases were evaporated under vacuum. The residue was filtered through silica gel (heptane / dichloromethane) and crystallized from isopropanol to give compound 1 (54.51 g, yield 81.32%). Mass Spectrum m / z: 676.29 (calculated: 676.31). Theoretical element content (%)C 51 h 36 N 2 : C, 90.50; H, 5.36; N, 4.14 Measured element content (%): C, 90.51; H, 5.35; N, 4.15. It was confirmed above that the obtained product was the target product 1.

Embodiment 2

[0053] Preparation of compound 16

[0054]

[0055] Preparation of compound 16

[0056] Compound 16 was obtained by replacing 1-1 in Example 1 with 16-1 shown above, and 1-2 with 16-2 shown above. Mass Spectrum m / z: 777.31 (calculated: 777.33). Theoretical element content (%)C 58 h 39 N 3 : C, 89.55; H, 5.05; N, 5.40 The measured element content (%): C, 89.53; H, 5.06; N, 5.41. It was confirmed above that the obtained product was the target product 16.

Embodiment 3

[0058] Preparation of compound 27

[0059]

[0060] Preparation of compound 27

[0061] Compound 27 is obtained by replacing 1-1 in Example 1 with 27-1 shown above, and 1-2 with 27-2 shown above. Mass Spectrum m / z: 776.32 (calculated: 776.35). Theoretical element content (%)C 59 h 40 N 2 : C, 91.21; H, 5.19; N, 3.61 The measured element content (%): C, 91.22; H, 5.18; N, 3.62. It was confirmed above that the obtained product was the target product 27.

Abstract

The invention provides a triarylamine derivative and an organic electroluminescence device thereof, and belongs to the technical field of organic photoelectric materials. The derivative has a structure as shown in a formula (I), a triarylamine structure is introduced to one end of the derivative, and the transmission property of a current carrier is increased. At a specific position, structurally,the obtained materials have high glass-transition temperature and melting points by introducing fluorenyl, joule heat is generated between an organic layer and a metal electrode, and the derivative has high heat resistance and high durability at high temperature and can prevent crystallization. A synthetic method is simple and easy to operate, and the organic electroluminescence device prepared from the triarylamine derivative has good electroluminescence efficiency and long service life.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a triarylamine derivative and an organic electroluminescence device thereof. Background technique [0002] With the progress of the information industry, traditional displays can no longer meet people's requirements, such as: cathode ray tube (CRT) displays have large volume and high driving voltage; liquid crystal displays (liquid crystal display, LCD) have low brightness and narrow viewing angles. , The operating temperature range is small; the plasma display panel (PDP) is expensive, the resolution is not high, and the power consumption is large. [0003] Organic light-emitting diodes (organic light-emitting diodes, OLEDs) as a new display technology has unparalleled advantages in various performances of existing display technologies, such as full solid state, self-luminous, high brightness, high resolution , wide viewing angle (above 170 degrees), fas...
