Embodiment 1

[0067] Synthesis of monomer

[0068] 1) Monomer M1:

[0069] Synthesize monomer M1 according to the route shown in the following formula, and the specific process includes:

[0070]

[0071] Choose a 100mL three-necked flask, connect it with Ar protective gas, spherical condenser, and ground plug in sequence. Under an argon atmosphere, N-(4-aminophenyl)-carbazole (3.22 g, 12.5 mmol) was dissolved in ethanol, heated slightly to 60° C. and stirred to fully dissolve. After dissolving, when the solution was slightly cooled, 5,5'-methylene-disalicylaldehyde (1.28 g, 5 mmol) was added, stirred and heated under reflux for 8 hours to obtain monomer M1. After the reaction was completed, the product was washed with water and ethanol in an ultrasonic cleaner after suction filtration, and the solid product was collected by suction filtration. The product was recrystallized using a mixed solvent of DMF, ethanol and water. The whole process of recrystallization was carried out under ...

Embodiment 2

[0084] Prepare P1

[0085] Add monomer M2 (2.82g, 3.00mmol), 4,4-difluorodiphenyl sulfone (0.76g, 3.00mmol), potassium carbonate (0.41g, 3.00mmol), and sulfolane 9mL to the Paddle (mechanical stirring), three-neck flask with condenser tube oil-water separator. The toluene in the oil-water separator is flush with the outlet of the branch pipe. Under the protection of argon, the temperature was controlled at 160°C, and the mixture was heated and stirred. When turbidity appears in the oil-water separator, carry water for 3 hours. When the two-phase interface in the oil-water separator no longer moves, the toluene is distilled off. Then the temperature was raised to 200° C., and the viscosity of the system rose rapidly after 2 hours of reaction. After the reaction was completed, the heating and stirring were stopped, and the mixture in the bottle was poured into distilled water while it was still hot. The off-white strip solid was obtained, and the solid was crushed into powd...

Embodiment 3

[0091] Prepare P2

[0092] Add monomer M 4 (2.73g, 3.00mmol), 4,4'-difluorodiphenyl sulfone (0.76g, 3.01mmol), potassium carbonate (0.39g, 2.86mmol), and sulfolane 9mL to the Fluorine stirring paddle (mechanical stirring) and a three-necked flask with a condenser oil-water separator. The toluene in the oil-water separator is flush with the outlet of the branch pipe. Under the protection of argon, the temperature was controlled at 160°C, and the mixture was heated and stirred. When turbidity appears in the oil-water separator, carry water for 3 hours. When the two-phase interface in the oil-water separator no longer moves, the toluene is distilled off. Then the temperature was raised to 200°C, and after 6 hours of reaction, the viscosity of the system rose rapidly and imploded, and the sample in the reactor was in the shape of jelly. After the reaction is over, stop heating and stirring, and pour the mixture in the bottle into distilled water while it is still hot to obtain...

Abstract

A polyarylether polymer containing a photoelectric functional group, a preparation method and an application thereof belong to the technical field of polymer materials. From the perspective of molecular design, the present invention introduces carbazole, triphenylamine, etc., which contain conjugated photoelectric active groups, into polymer side chains, and modifies the positions of the corresponding groups to continuously improve the performance of the material. Polyarylether polymers containing photoelectric functional groups were prepared by homopolymerization. At the same time, due to the use of nucleophilic substitution polycondensation method during polymerization, not only higher molecular weight polymers can be obtained, but also the degree of polymerization can be controlled. The 5% thermal weight loss of polyarylether polymers containing photoelectric functional groups provided by the invention is above 300°C, and can be dissolved in tetrahydrofuran, dichloromethane, chloroform, N, N'-dimethylformamide, Organic solvents such as N, N'-dimethylformamide, N-methylpyrrolidone, etc., can exhibit the photoelectric properties of corresponding photoelectrically active groups.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyarylether polymer containing photoelectric functional groups, a preparation method and an application thereof. Background technique [0002] From ancient times to the present, polymer materials have been of great help to the development of human civilization. From the use of cotton to the present, a variety of functional polymer materials have met the different needs of human beings. In the 21st century, with the development of science and technology and the popularization of the Internet, the development of functional polymer materials has been promoted. It is inseparable from people's production and life, and the direction and trend of material development will directly determine the development of social economy. In recent years, with the continuous improvement of people's living standards, the requirements for polymer materials are also getting hi...
