Embodiment 1

[0170] Embodiment 1: the synthesis of compound H11

[0171]

[0172] In the three-necked flask, under the protection of nitrogen, add 0.01mol raw material A, 0.012mol raw material B, 0.02mol sodium carbonate, mixed solvent (150ml toluene, 45ml H 2 O), then add 1×10 -4 mol tetrakis(triphenylphosphine)palladium Pd(pph 3 ) 4 , heated to 105°C, refluxed for 24 hours, sampling and pointing plate, showing no remaining iodide, the reaction was complete. Naturally cooled to room temperature, filtered, and the filtrate was subjected to vacuum rotary evaporation (-0.09MPa, 85°C), passed through a neutral silica gel column (silica gel 100-200 mesh, the eluent was chloroform:n-hexane=1:2 (volume ratio) ), to obtain intermediate M. Elemental analysis structure (molecular formula C 24 h 15 BrClN): Theoretical C 66.61; H 3.49; Cl 8.19; Br 18.46; N 3.24; Found: C 66.57; H 3.45; Cl 8.14; MS: The theoretical value is 431.01, and the measured value is 431.19.

Description

technical field [0001] The present invention relates to the field of semiconductor technology, and more specifically, relates to a novel aromatic amine compound and its use as a hole transport material in an organic electroluminescent device. A light emitting device, and a display device comprising the organic electroluminescent device. Background technique [0002] The carriers (holes and electrons) in the organic electroluminescent device (OLED) are respectively injected into the device by the two electrodes of the device under the drive of the electric field, and meet in the organic light-emitting layer to recombine and emit light. High-performance organic electroluminescent devices require various organic functional materials to have good photoelectric properties. For example, as a charge transport material, good carrier mobility is required. The injection and transport characteristics of hole injection layer materials and hole transport layer materials used in existin...
