Abstract

The invention belongs to the technical field of non-linear hybridization optical materials, and particularly relates to a method for preparing a light conversion composite nanopore material. According to the method, hydroxyl naphthalenone organic molecules are synthesized and modified by an organic synthesis method, so that a functionalized molecular bridge is obtained; furthermore, functionalized hydroxyl naphthalenone is added into tetraethoxysilane to generate cohydrolysis polycondensation, so that an organic and inorganic hybridized pore material with a regular and organized height duct structure is formed; and rare earth ions and small molecules are added for coordination, so that a rare earth organic or inorganic or small-molecule hybridized material is formed. According to the method, the organic molecule with an electronic conjugation system and an electronic transferring structure is connected with the rare earth ions due to coordination reaction, and the rare earth ions are connected with organic molecules, so that organic molecules, inorganic molecules and rare earth molecules are connected through strong covalent bonds and coordination bonds, and a nonlinear optical composite nanopore material with stable chemical and thermal properties and a regular surface appearance can be obtained. The experimental condition of the method is mild; the light conversion composite nanopore material can be directly obtained at room temperature; the operability is high; and the reproducibility is high. The obtained product receives visible light and performs excitation energy transmission, so that the quality is stable, and the appearance is regular.
