Embodiment 1
[0083] Preparation of compound 1
[0084]
[0085] Preparation of Compound 1-3
[0086] Under the protection of nitrogen, 1-1 (32.10g, 100.08mmol), 1-2 (16.70g, 100.08mmol), potassiumcarbonate (1.24g, 9.00mmol), and toluene 200mL were added to a 2L reactor and stirred. The temperature in the reactor was raised to 70°C, and Pd(PPh 3 ) 4 (1.04g, 0.90mmol), stirred with 100mL distilled water, stirred and refluxed for 11h, fully reacted. After adding 70mL of distilled water to terminate the reaction, filter under reduced pressure, wash the solid with distilled water, and then use acetone, toluene, THF to recrystallize, after the solid is obtained, sublimate, and toluene recrystallize to obtain 29.13g of intermediate 1-3, with a yield of 80.44 %.

Abstract
The invention provides an organic compound and an organic electroluminescent device thereof, and belongs to the technical field of organic photoelectric materials. The compound has a structure shown in formula (I), the organic compound introduces hetero atoms, and the intramolecular hetero atom has the factor for determining the HOMO / LUMO level, the bandgap energy and the T1 value of the core; acridine, phenothiazine, phenoxazine, dibenzofuran, dibenzothiophene, carbazole, fluorene and the like are introduced to a specific position of the organic compound for facilitating receiving electrons,so that the organic compound has good transmission performance; A bridging structure is introduced, on one hand, the molecular weight of the compound can be increased, the obtained material has a highglass transition temperature and can prevent crystallization, and on the other hand, the compound has a certain twist on the space stereo structure, and the film forming property is improved. The organic electroluminescent device is prepared by using the compound as the main material in the light-emitting layer, has the advantages of low driving voltage and high luminous efficiency, and is an organic luminous material with excellent performance.
Description
technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an organic compound and an organic electroluminescent device. Background technique [0002] With the progress of the information industry, traditional displays can no longer meet people's requirements, such as: cathoderay 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 all solid-state, self-luminous, high brightness, high resolution rate, wide viewing angle (above 170 degrees), fast response...
