The invention discloses a preparation method of a porphyrin coupled silicon dioxide organic-inorganic nonlinear optical material, which comprises the following steps: 1. heating and reflowing a mixed solution of Msco-tetra-(4-carbomethoxyphenyl) porphyrin copper and gamma-aminopropyltriethoxysilane at the temperature of 160 to 250 DEG C for 10 to 60 hours to obtain a transparent deep red liquid; 2. dissolving a reaction product of step 1 and metal alkoxide into anhydrous ethanol, and stirring at room temperature for 1 to 2 hours; 3. dropwise adding a (H2O) / (C2H5OH) mixed liquid into the reaction product of step 2 at the room temperature for hydrolysis and polymerization reaction for 1 to 5 hours; and 4. pouring the obtained transparent sol into a glass or plastic utensil, sealing with a thin film, ageing at the room temperature for 35 to 45 days, and pricking a hole on the thin film every day to finally prepare compound dried gel. The invention has the advantages that the monomer doping concentration of porphyrin molecules in a gel solid medium can be greatly improved, and the molecular energy level structure and the spectral characteristic of the porphyrin molecules in the gel medium are kept.
