Abstract

The invention relates to the technical field of organic materials and provides a thienothiophene quinoid organic photoelectric material. The material is a compound which is shown as a structural formula (I); in the formula, R1, R2, R3, R4, R5 and R6 are selected from H, C1-C20 alkyl group or C1-C20 alkoxyl group; and m and n are integers of 0-10. The invention also provides a preparation method and application of the thienothiophene quinoid organic photoelectric material. Since the thienothiophene quinoid organic photoelectric material has a quinoid thiophene ring and a cyano group, wider spectral response is guaranteed, the photoelectric conversion efficiency of the material is increased, and better thermal stability and environmental stability are shown.

Description

technical field

[0001] The invention belongs to the technical field of organic materials, and in particular relates to a thienothiophene quinone type organic photoelectric material, its preparation method and 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.

[0003] In order to make full use of the energy irradiated by sunlight, people continue to develop new materials that can absorb sunlight. Among them, inorganic sem...
