specific Embodiment approach 1

[0022] Specific implementation mode 1: This implementation mode provides a preparation method for substituted anthracene derivatives, which is specifically completed according to the following steps:

[0023] 1. Add benzene and N-bromosuccinimide to anthracene, heat to 35°C~45°C, add benzoyl peroxide to it, heat to reflux with stirring, and the reflux time is 6h~ 12h, then, cool to 20°C~30°C, pour out the upper liquid, filter the remaining solid part, wash with water, and dry at 60°C~80°C to obtain 9,10-dibromoanthracene; among them, benzene The ratio of the volume of anthracene to the amount of anthracene is (1000mL~3000mL):1mol, the molar ratio of N-bromosuccinimide to anthracene is (1.5~3.0):1, the ratio of benzoyl peroxide to anthracene The molar ratio is (7.5×10 -4 ~1.0×10 -3 ):1;

[0024] 2. Under the condition of nitrogen protection, add toluene I, ethanol, water I, substituent boronic acid compound, potassium carbonate and tetrakis (triphenylphosphine) palladium to ...

specific Embodiment approach 2

[0026]Embodiment 2: The difference between this embodiment and Embodiment 1 is that the substituent boronic acid compound in Step 2 is phenylboronic acid, 1-naphthaleneboronic acid or 2-naphthaleneboronic acid. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0027] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the substituents in the 9,10-bis(substituent) anthracene obtained in Step 2 are phenyl, 1-naphthyl or 2-naphthyl. Others are the same as in the first or second embodiment.

[0028] The structural formula of 9,10-di(substituent)anthracene described in this embodiment is:

Abstract

The invention relates to a preparation method of a derivative for substituting anthracenes, belongs to the field of preparation methods of derivatives for substituting the anthracenes, and aims at solving the technical problem that an existing preparation method of the derivative for substituting the anthracenes is complicated in operation and high in reaction condition. The preparation method of the derivative for substituting the anthracenes comprises the steps of firstly, preparing 9,10-dibromo anthracene; and secondly, preparing 9,10-second (substituent group) anthracene. The preparation method of the derivative for substituting the anthracenes can further comprises the steps of: firstly, preparing 9-(substituent group I) anthracene, secondly, preparing 9-bromine-10-(substituent group I); and thirdly, preparing 9-(substituent group II)-10-(substituent group I) anthracene. The preparation method of the derivative for substituting the anthracenes is simple in preparation process, low in reaction condition, and simultaneously, yield of the derivative for substituting the anthracenes obtained by the preparation method can achieve 95%. The preparation method can be applied to the field of blue light organic electroluminescence materials.

Description

technical field [0001] The present invention relates to the field of processes for the preparation of substituted anthracenes. Background technique [0002] Organic Light Emitting Display (Organic Light Emitting Display, referred to as OLED), because of its own self-illumination, no backlight is needed, only the organic light-emitting material is coated on a very thin substrate, and a low voltage is applied to both ends of the device. , these organic materials will emit light, so OLED screens can be made thinner and lighter, have a wider viewing angle, require lower voltage, lower energy consumption, and can produce large-sized and flexible panels, known as As the star flat panel display product of the 21st century, "dream display" is also known as the ultimate display of the future. [0003] Among organic light-emitting materials, many blue-light materials have been reported in many literatures. The structures of these materials can be roughly classified into anthracene de...
