Carbon nanotubes are novel nanomaterials with one-dimensional nanostructures and possess many unique physical and chemical properties. Porphyrin strongly absorbs visible light and its large π-conjugated system gives it good electron-donating ability and can be used as artificial photosynthesis The light-capturing unit of the action system combines the carbon nanotubes having electron accepting ability with the porphyrin, and covalently and non-covalently modifying the carbon nanotubes by the porphyrin, so as to improve the dissolution and dispersion properties of the carbon nanotubes in the solvent , At the same time realize the efficient electron transfer between porphyrin and carbon nanotubes and form the porphyrin-carbon nanotube complex with unique photoelectric and optical properties. These materials have good application prospects in the research of carbon nanotubes and porphyrins In recent years, the progress of the research on the construction methods and properties of such complexes has been reviewed.
