A benzophenone-cored dianhydride building block
As an intermediate for the synthesis of polyimides in application of photosensitizers, high-performance polymers and OFETs
3,3',4,4'-Benzophenonetetracarboxylic dianhydride (BTDA, CAS number 2421-28-5) is derived from benzophenone with two dianhydride on both terminals. The primary use of 3,3',4,4'-Benzophenonetetracarboxylic dianhydride is for synthesizing polyimide with primary amines undergoing nucleophilic substitution followed by condensation reactions. Benzophenone-cored polyimide is used in photocatalytic dye degradation applications such as methylene blue in water. Potentially it can extend its applications to dye-sensitized solar cells (DSSCs) and photocatalytic reactions.
The polyimide/copolymer formed by BTDA has shown high thermal stability and good mechanical properties. This polyimide is an electret and used as a dielectric layer for high performance OFET memory devices.
