3,3',4,4'-Benzophenonetetracarboxylic dianhydride is an organic compound commonly used in the synthesis of dyes, fluorescents and photosensitive materials. In the field of dyes, BTDA is used as a dye for clothing, paper, and plastics, where it imparts rich colors to these materials.
In terms of fluorescent agents, 3,3',4,4'-Benzophenonetetracarboxylic dianhydride is often used as a fluorescent labeling molecule. It can be used as a fluorescent probe for detecting the presence and quantification of biomolecules and chemical molecules.
In terms of photosensitive materials, 3,3',4,4'-Benzophenonetetracarboxylic dianhydride can be used as one of the components of photosensitizers and photosensitive materials, such as photosensitive polyimides, polyimide foams and other materials. When BTDA is irradiated with light of a specific wavelength, it undergoes a photochemical reaction that releases energy, which triggers a specific change in the properties of the photosensitive material.
