▎ 摘  要

NOVELTY - Porphyrin edge modified graphene oxide nano hybrid material is prepared by reacting aldehyde porphyrin with ortho-diketone on the edge of graphene oxide. USE - Porphyrin edge modified graphene oxide nanohybrid material used for preparing more functionalized photo-catalysis, light capture, solar battery, and light limiting element. ADVANTAGE - The hybrid material combines porphyrin and graphene oxide at the electronic structure and chemical structure feature, the steady state absorption of the red shift, large quenching fluorescence and enhanced non-linear optical absorption performance, and verifies the new hybrid material prepared by the new method of effective electronic coupling and transfer efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing porphyrin edge-modified graphene oxide hybrid nanomaterial, which involves adding the graphite powder into concentrated nitric acid, sequentially adding sodium nitrate, potassium permanganate and hydrogen peroxide for full oxidation, and filtering, washing and drying to obtain graphene oxide, dissolving 5,15-bis-(3,5-di-tert.-butylphenyl)-10,20-bis-phenylporphyrin in dichloromethane, adding copper acetate dissolved in methanol solution in advance under stirring for reaction to obtain 5,15-bis- (3,5-di-tert.-butylphenyl)-10,20-bis-phenylporphyrin copper, adding 5,15-bis-(3,5-di-tert.-butylphenyl)-10,20-bis-phenylporphyrin copper in 1,2-dichloroethane solution into dimethylformamide pretreated with phosphorus oxychloride for reaction, and separating the obtained reaction product to obtain 10-aldehyde-5,15-bis-(3,5-di-tert.-butylphenyl)-20-phenylporphyrin copper, dissolving 10-aldehyde-5,15-bis-(3,5-di-tert-butylphenyl)-20-phenylporphyrin copper in a dichloromethane solution, dropwise adding a mixture of concentrated sulfuric acid and trifluoroacetic acid under stirring to obtain 10-aldehyde-5,15-bis-(3,5-di-tert-butylphenyl)-20-phenylporphyrin with copper ions, dispersing 10-aldehyde-5,15-bis-(3,5-di-tert.-butylphenyl)-20-phenyl porphyrin and graphene oxide in a mixed solution of dichloromethane and acetic acid for performing ultrasonic treatment, and adding ammonium acetate under stirring, heating, reacting and filtering the obtained reaction product to obtain the target product.
