Embodiment 1

[0070] Embodiment 1: the synthesis of C-8-1

[0071]

[0072] a) Under nitrogen atmosphere, bis(4-bromophenyl)diphenylmethane (4.4g) and 9-phenylcarbazole-3-boronic acid (3g) were completely dissolved in 120mL tetrahydrofuran in a 250ml round bottom flask , 60 mL of 2M aqueous sodium carbonate solution was added, and then tetrakis-(triphenylphosphine)palladium (0.3 g) was added, and the mixture was heated and stirred for 12 hours. After cooling to room temperature, the aqueous layer was removed. Add 100 mL of dichloromethane, and wash twice with 30 mL of saturated brine. The dichloromethane layer was dried over anhydrous magnesium sulfate, and concentrated in vacuo. Then dichloromethane:ethyl acetate (20:1~2:1) was used as eluent to purify and separate on a silica gel column to obtain (4-(9-phenylcarbazol-3-yl)phenyl)- (4-Bromophenyl)diphenylmethane, white solid 5.8 g (90% yield); MS (ESI): 640.2 (M+H).

[0073] b) Dissolve (4-(9-phenylcarbazol-3-yl)phenyl)-(4-bromophen...

Embodiment 2

[0075] Embodiment 2: the synthesis of S-8-1

[0076]

[0077] Similar to the synthesis conditions of Example 1, using bis(4-bromophenyl)diphenylsilane as a raw material, the final product S-8-1 can be obtained through the same reaction conditions and separation and purification steps, MS (ESI) : 809.3(M+H)

Embodiment 3

[0078] Embodiment 3: the synthesis of S-8-31

[0079]

[0080] Similar to Example 2, 9-phenylcarbazole-3-boronic acid was replaced with 9-biphenylcarbazole-3-boronic acid, and S-8-31 could be obtained through the same reaction conditions and separation steps. MS (ESI): 885.3 (M+H) glass transition temperature 143 degrees.

Abstract

The invention provides a compound for an organic optoelectronic device and an organic optoelectronic element containing the compound and application and specifically discloses a compound shown as a chemical formula 1. A hole injection layer, a hole transmission layer, an electron blocking layer or a light emitting layer of an organic light emitting device (OLED) contains the compound. A donor group with high thermal stability and a receptor group are connected through a non-conjugated linkage system and the obtained compound can form an intermolecular charge transfer excitation state to realize light emission. Meanwhile, the compound has high glass transition temperature and good thermal and light stability. A preparation method of the compound is simple and large-scale production is easyto realize; the compound is used as a functional layer and is applied to an OLED element; the obtained element has the advantages of high efficiency, low operation voltage and long service life, can be applied to a display device or a light source device and has a very good commercial application prospect.

Description

technical field [0001] The invention belongs to the technical field of organic optoelectronics, and in particular relates to a compound used for an organic optoelectronic device and an organic optoelectronic device comprising the same. Background technique [0002] Organic optoelectronic devices, especially organic electroluminescent elements (OLEDs), organic field-effect transistors (OFETs), and organic solar cells have attracted many scientists and industries. Among them, OLED or diode, as a new generation of flat-panel display technology, has gradually entered people's field of vision. Its wide application prospects and rapid technological advancement in recent years have made OLED one of the most popular researches in the field of flat-panel information display and scientific research product development. [0003] The research on organic electroluminescent materials began in the 1960s. Until 1987, when Tang et al. produced organic electroluminescent devices for the first...
