Chemical Properties

off-white crystalline powder

Chemical Properties

Dicyclohexyl-3,4,3',4'-tetracarboxylic dianhydride (HBPDA) is a dianhydride building block with a flexible bicyclohexyl core. The polyimides synthesized form dicyclohexyl-3,4,3',4'-tetracarboxylic dianhydride are often transparent, because of the flexible polymer backbones. Thus, it can be used as shielding layers in photovoltaics. The refractive index of the polyimides can be tuned by TiO2 fillers for matching the ZnO layer (the electron transport layer), to reduce the reflection losses at the ZnO interface.

Uses

HBPDA is a polyimide precursor that is used to prepare polyimides by reaction with diamines and dianhydrides.  And it is used in the formation of coatings on various materials including metals and plastics.
