Abstract

The invention belongs to the field of mesoporous materials, and relates to mesoporous organic-inorganic silicon oxide with luminescent property and a preparation method thereof. The mesoporous organic-inorganic silicon oxide with luminescent property is prepared by hydrolytic condensation of organic silicon with aggregation-induced emission property. The organic silicon compound with an aggregation-induced emission effect is synthesized, the synthesis method of the compound is simple, and the compound has the luminescence property. An external template method is adopted, the operation is easy and convenient, the raw material consumption is low, and a template is easy to remove. The application of the mesoporous organic-inorganic hybrid silicon oxide with the fluorescent property is widened.

Description

technical field [0001] The invention belongs to the field of mesoporous materials, and relates to a mesoporous organic-inorganic silicon oxide with luminous performance and a preparation method thereof. Background technique [0002] Mesoporous organic-inorganic hybrid silica refers to the bridge-type organosiloxane, under the guidance of the template agent, the organic group-R- and silicon are alternately arranged and uniformly distributed in the framework of the organic-inorganic hybrid Silicon oxide material. Since Academician Tang Benzhong and his colleagues discovered the phenomenon of aggregation-induced emission (AIE) in 2001, they introduced aggregation-induced emission into mesoporous organic-inorganic hybrid silicon oxide, so that it can also have strong fluorescence properties in the aggregated state, broadening the field of Its applications in cell imaging, chemical sensing and CPL materials, etc. Many literatures report the preparation of mesoporous organic-ino...
