Abstract

The invention provides triazine functionalized silsesquioxane based hybrid porous polymer, its preparation method and its application in catalytic degradation of dye pollutants. The invention uses octavinylsilsesquioxane (OVS) and triazine monomers (TAs) substituted by bromophenyl or thiophene as raw materials to prepare a hybrid porous material with photocatalytic performance through Heck reaction; the preparation method is simple, The reaction conditions are easy to realize; the obtained material has good chemical stability, thermal stability and fluorescence characteristics, which greatly improves the specific surface area and pore volume of the silsesquioxane-based hybrid porous material, and exhibits high efficiency for dyes in wastewater Catalytic degradation ability has great potential application value in the field of sewage treatment.

Description

technical field [0001] The invention relates to a triazine-functionalized silsesquioxane-based hybrid porous polymer, a preparation method and application thereof, and belongs to the technical fields of polymer material preparation, catalytic degradation, sewage detection and treatment. Background technique [0002] In recent years, more and more synthetic dyes have been widely used in industries such as textile and printing. Many dyes used in large quantities, due to their toxicity, difficulty in biodegradation, and potential carcinogenicity and mutagenicity, etc., so that their release into the environment will cause serious ecological damage. These custom-designed and synthesized dye molecules, such as azo-based dyes (Congo red, CR), thiazide-based dyes (methylene blue, MB) and fluorescein-based dyes (rhodamine B, RB; sangrin T, ST), usually have The chromophore unit has high bond energy, so it is very stable; at the same time, its ionic structure also makes it have high...
