Embodiment 1

[0025] Add 500 mg of multi-walled carbon nanotubes to 150 mL of a mixed strong acid solution consisting of concentrated sulfuric acid and concentrated nitric acid in a volume ratio of 3:1, ultrasonically oscillate for 4 hours, pour into deionized water, and stand for 12 hours, filter and wash with water to neutral, and then dried to obtain chemically etched carbon nanotubes; under the protection of nitrogen, 400 mg of the above-mentioned carbon nanotubes with carboxylic acid were placed in 100 mL of thionyl chloride and refluxed for 36 hours. Distilled under high pressure to remove excess thionyl chloride, and vacuum-dried to obtain acid-chlorinated carbon nanotubes; 50 mg of the above-mentioned acid-chlorinated carbon nanotubes were dispersed in 25 mL of N-methylpyrrolidone, and after ultrasonication for 15 minutes, 15 mg The 2,3-dibromo-1-propanol was reacted continuously for 24 hours under nitrogen protection at 100°C. After cooling to 25°C, it was poured into 100mL ethanol ...

Embodiment 2

[0033] Same as Example 1, but the amount of alkynylated poly(3-hexylthiophene) in step (4) is changed from 15 mg to 7.5 mg, and step (5) contains 4-phthalonitrile and poly(3-hexylthiophene) The amount of carbon nanotubes changed from 15 mg to 17.5 mg, and the others remained unchanged.

Embodiment 3

[0035] Same as Example 1, but the amount of alkynylated poly(3-hexylthiophene) in step (4) is changed from 15 mg to 22.5 mg, and step (5) contains 4-phthalonitrile and poly(3-hexylthiophene) The amount of carbon nanotubes changed from 15 mg to 10 mg, and the others remained unchanged.

Abstract

The invention belongs to the technical field of organic / inorganic nano-composite material, in particular to a method for preparing a phthalocyanine-carbon nanotube-polythiophene composite light-sensitive material by a click chemical method. Compared with the common esterification method, amide method, and the like, the method has the characteristics of moderate condition, fast reaction speed and high composite efficiency, etc.; the dispersion uniformity and the storage stability of the obtained phthalocyanine-carbon nanotube-polythiophene composite material are improved significantly; the phthalocyanine-carbon nanotube-polythiophene composite material prepared in the click chemical method has higher light sensitivity, compatibility and thermal stability as well as excellent solubility andelectro-optical property. Products prepared by the invention are new generation green and environment-friendly high-performance chemical products which can be applied to fields such as conductive materials, solar cell materials, photoconductive materials and photoelectric conversion materials, etc.

Description

technical field [0001] The invention belongs to the technical field of organic / inorganic nanocomposite materials, and in particular relates to a method for preparing a phthalocyanine-carbon nanotube-polythiophene composite photosensitive material by a click chemistry method. Background technique [0002] With the depletion of mineral energy such as coal, oil, and natural gas, the global energy shortage problem has become more and more prominent. The energy problem has become a major problem encountered in the economic and social development of all countries in the world, and has seriously affected the survival and development of human beings. People urgently need to find other alternative energy sources. Solar energy has the advantages of inexhaustible, safe, reliable, and pollution-free, and has attracted more and more attention. However, as an industrial energy source, solar energy has the disadvantage of low energy density. In order to make full use of this cheap, envir...
