Embodiment 1

[0062] The nitrogen-containing thiophene organic photoelectric material of the present embodiment 1 uses R 1 , R 2 for hexyl, R 3 Take 3-ethyl-heptyl as an example, its structural formula is as follows:

[0063]

[0064] It can be seen from the structural formula that the nitrogen-containing thiophene organic photoelectric material in Example 1 has a symmetrical structure, with a hexathiophene ring and two pairs of cyano groups, and the cyano groups serve as electron-withdrawing groups. Through this uniform and symmetrical structure, nitrogen-containing Thiophene organic optoelectronic materials have relatively good light absorption properties and optoelectronic properties.

[0065] The preparation method of this hexathiophene adopts the concrete operations of the first scheme as follows:

[0066] 1) Preparation of 2-((2-bromo-5-(5-hexylthiophen-2-yl)thiophen-3-yl)methylene)malononitrile, whose structural formula is as follows:

[0067]

[0068] Since the nitrogen-co...

Embodiment 2

[0075] The nitrogen-containing thiophene organic photoelectric material in Example 2 takes the same final product of hexathiophene as in Example 1 as an example, and the preparation method of the hexathiophene is specifically operated as follows according to the second scheme.

[0076] 1) Preparation of 2-(2-(3-formyl-5-(5-hexylthiophen-2-yl)thiophen-2-yl)-N-[1-(2'-ethylhexyl)-3-ethane ylheptyl]-dithiophene[3,2-b:2',3'-d]pyrrol-5-yl)-5-(5-hexylthiophen-2-yl)thiophene-3-carbaldehyde, whose structural formula is as follows Shown:

[0077]

[0078] Similarly, the nitrogen-containing thiophene organic photoelectric material in Example 2 has a symmetrical structure, therefore, the compounds A and B in this step have the same structure, and only one kind of raw material needs to be provided to directly perform step 1), thus also The preparation process is simplified and the cost is reduced, and the production rate is higher than when different compounds A and B are used. Concre...

Abstract

The invention relates to the organic material technology field. An organic photoelectric material containing nitrogen thiophene is provided, and comprises a compound expressed by structural formula (1), wherein R1, R2, R3 and R4 are same or different alkyls expressed as H or C1-C20; m and n stand for same or different integers between 0-10. The invention also provides a manufacturing method and application of the organic photoelectric material containing nitrogen thiophene. Because of possessing thiophene ring and cyan, the organic photoelectric material containing nitrogen thiophene has wide spectrum response, good heat stability and environmental stability. Synthetic route in manufacturing method of the organic photoelectric material containing nitrogen thiophene is simple, thereby manufacturing cost is low and application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of organic materials, and in particular relates to a nitrogen-containing thiophene organic photoelectric material, its manufacturing method and its application. Background technique [0002] Today's world economy is mainly based on fossil energy, such as coal, oil and natural gas. However, these non-renewable fossil energy sources are constantly being exhausted. Since the beginning of the 21st century, global energy issues and the ensuing environmental pollution and climate warming have become increasingly prominent and gradually intensified. Solar energy is considered to be one of the most promising renewable energy sources because of its widespread and vast distribution, large amount of resources, no pollution, cleanliness, safety, and easy access. Solar cells directly convert sunlight energy into electrical energy, which is a practical and effective way to utilize solar energy. However, currently comme...
