Embodiment 1

[0055] The specific reaction route is as follows:

[0056]

[0057] Proceed as follows:

[0058] 5-(5-Bromothiophen-2-yl)-1,3,4-oxadiazole-2(3H)-thione (4)

[0059] Add 5-bromothiophene-2-carbohydrazide (0.8843g, 4.0mmol), potassium hydroxide (0.3366g, 6.0mmol), 35mL of absolute ethanol, CS to a round bottom flask 2 (0.5484 mL, 8.0 mmol), magnetically stirred and refluxed, 0.5 mL of carbon disulfide was added every 2.0 h, twice, and the reaction was stopped after 8.0 h. After the reaction was completed, the solvent was removed by rotary evaporation under reduced pressure, 30 mL of water was added, vigorously shaken, and the filtrate was obtained by filtration. Adjust the pH to about 2-3. A large amount of light yellow solid precipitated out. The light yellow solid 4 (0.843g, yield 80.1) %).

[0060] 1 The H NMR results are as follows: δ 7.63 (d, J = 4.0 Hz, 1H), 7.44 (d, J = 4.0 Hz, 1H).

[0061] 5-(5-Bromothiophen-2-yl)-3-hexyl-1,3,4-oxadiazole-2(3H)-thione(6)

Abstract

The invention discloses a small oligothiophene organic molecule and a preparation and application method thereof. The small oligothiophene organic molecule is a small oligothiophene organic molecule compound containing oxadiazole, which is high in thermal stability and solubility and has a relatively broad absorption spectrum in the ultraviolet-visible spectrum. When serving as a photovoltaic material and applied to a small organic molecule solar battery, the small oligothiophene organic molecule can embody a good photovoltaic conversion function and achieve good antibacterial effects and accordingly can serve as antibacterial drugs for bacteria such as Gram-positive bacteria and Gram-negative bacteria.

Description

Technical field [0001] The invention relates to an organic small molecule photovoltaic material and a preparation method and application thereof, in particular to an oligothiophene organic small molecule, a preparation method thereof, and application in organic small molecule solar cells or application in antibacterial drugs , Belongs to the field of organic photoelectric materials and biomedicine. Background technique [0002] In today's world, with the rapid progress of human civilization and the rapid development of society and economy, the demand for energy is increasing. However, people's excessive use of fossil fuels as conventional energy sources has led to an energy crisis, which has led people to search for and develop new energy sources. Solar energy has received more and more attention as a clean and environmentally friendly renewable energy. Solar cells that convert solar energy into electrical energy have become a hot spot for scientists. Organic photovoltaic mater...
