Problems solved by technology

However, many studies have found that when porphyrin is doped into inorganic gels using this technology, it is very easy to polymerize due to the shrinkage of the gel structure and the volatilization of the solvent, resulting in a serious concentration quenching effect.

Abstract

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.

Description

technical field [0001] The invention relates to a method for preparing an organic-inorganic photoelectric functional material, in particular to a method for preparing a porphyrin-coupled silicon dioxide organic-inorganic nonlinear optical material. Background technique [0002] Organic-inorganic composite materials are a new frontier research field that has developed rapidly since the mid-1980s. This material has the characteristics of both organic and inorganic substances, and overcomes the limitations of a single organic or inorganic material. It is the result of the penetration of inorganic chemistry, organic chemistry, mesoscopic physics and material science. It has been used in high-tech It will become the most promising important composite material in the 21st century. [1-2] . [0003] The solution-gel (sol-gel) technology is to obtain the required materials through gradual hydrolysis and polymerization of precursor raw materials such as metal alkoxides or inorganic ...
