[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 an anthracene structure-based cavity transport material as well as a preparation method and the application thereof. The cavity transport material is a novel organic micromolecular cavity transport material taking anthracene as a core, an olefinic bond as a bridge and triarylated amine as a lateral group; the chemical structural formula is as shown in a formula (I): (the formula is as shown in the description), wherein R is a group consisting of triarylated amine and a derivative thereof; in the cavity transport material provided by the invention, the anthracene servesas the core, the olefinic bond is introduced to connect with the triarylated amine, and the large two-dimensional conjugate plane structure can increase the cavity migration rate; furthermore, the anthracene structure-based cavity transport material has a good plane accumulation effect, shortens the interaction distance of molecules and reinforces the cavity transport capability, so that the material can serve as a cavity transport material to be applied to electronic devices such as solar batteries and has a wide application prospect.

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...
