[0082] Synthesis of Example 1 Hole Transport Material JX-1

[0083] 1. Synthesis method

[0084] The specific synthesis route of JX-1, which is a hole transport material, is shown in the attached figure 1 shown.

[0085] This schematic diagram shows only an example of the synthesis method, and the method of the present invention is not limited to the related substances shown in the figure. Concrete synthetic steps are as follows:

[0086] 1. Synthesis of compound 1

[0087]

[0088] A 50mL two-necked bottle was used as the reaction vessel, and the reaction device was subjected to anhydrous treatment under argon protection. Add anthracene (2.67g, 15mmol, 1.0eq) and paraformaldehyde (2.972g, 33mmol, 2.5eq) into the two-necked flask, ventilate, and add hydrobromic acid (5mL, 30%wt HOAc) under stirring. Reaction in an oil bath at 60°C for 12 hours. The product was spin-dried under reduced pressure. Add toluene dropwise in an oil bath at 60°C and oscillate to dissolve the c...

Abstract

The invention discloses a hole transport material based on anthracene structure and its preparation method and application. The hole transport material is a new type of small organic compound with anthracene as the core, ethylenic bonds as bridges, and triarylamine as side groups. Molecular hole transport material, its chemical structural formula is shown in formula (I):; wherein, R is a group composed of triarylamine and its derivatives; the hole material provided by the present invention takes anthracene as the core and simultaneously introduces ethylenic bonds to connect triaryl Amine, its large two-dimensional conjugated planar structure can effectively improve hole mobility, and has a good planar stacking effect, which shortens the molecular interaction distance and strengthens the hole transport ability, so that this kind of material can be used as a hole Hole transport materials are used in electronic devices such as solar cells, and have broad application prospects.

Description

technical field [0001] The present invention relates to the technical field of hole transport materials, more specifically, to a hole transport material based on anthracene structure and its preparation method and application. Background technique [0002] With the continuous development of the economy and the continuous deterioration of the ecological environment, the energy is becoming increasingly exhausted, and the human demand for sustainable energy is increasing. Therefore, solar cells have been highly valued by countries all over the world. [0003] Perovskite solar cells are a new type of solar cells developed from dye-sensitized solar cells in recent years, which can effectively solve many shortcomings of dye-sensitized solar cells, so they have become a hot spot in solar cell research. At present, the photoelectric conversion efficiency of perovskite batteries has broken through, but there are still many problems, such as the degradation of perovskite in water, whi...
