Embodiment 1

[0031]Dissolve 0.244g of phenylphenacyl sulfoxide in 15ml of anhydrous pyridine and add it to a three-necked flask, then add 5ml of anhydrous pyridine solution with 0.048g of sodium hydride dropwise, and the entire solution is controlled at 70 ℃, after heating to reflux for 2 hours under the protection of nitrogen, a solution of 0.495 g of triethoxysilylisocyanate in 5 ml of anhydrous pyridine was added dropwise. After the dropwise addition, the temperature of the whole solution was controlled at 65° C., refluxed for 12 h under the protection of nitrogen, then cooled, and the solvent was distilled off under reduced pressure. The resultant was washed three times with 10 ml of cyclohexane to obtain a pale yellow oily liquid. The obtained oily organic bridge molecule system was dissolved in nitrogen, nitrogen-dimethylformamide and set aside. Dissolve 5ml of methyl methacrylate in 15ml of nitrogen, nitrogen-dimethylformamide, add it to a three-necked flask, control the temperatur...

Abstract

The invention relates to a preparation method of an organic / inorganic / polymeric composite luminescent material of sulfoxide functionalization rare earth, belonging to the technical field of luminescent high-molecular composite materials. The preparation method comprises the following steps of: modifying organic sulfoxide molecules by an organic synthesis method to obtain a functionalized molecular bridge; further assembling the organic sulfoxide molecular bridge, a high-molecular polymer and rare earth ions into a rare earth coordination compound through coordinate bonds; and finally obtaining xerogel through the hydrolytie polycondensation of the obtained rare earth coordination compound by a sol-gel method so that a long carbon chain organic high-molecular polymer is inlayed to a silicanetwork matrix, and thus obtaining the high-molecular composite material which has stable chemistry and thermodynamics property, regular surface appearance and characteristic fluorescence emission The preparation method has moderate experiment condition, direct obtaining at room temperature, high operability and good repeatability; and in addition, an obtained product has stable quality and regular appearance.
