An non-conjugated alicyclic dianhydride

Applied for polyimides synthesis in application of high-performance polymer, photovoltaics, and optoelectronics

Specifications | MSDS | Literature and Reviews

Dicyclohexyl-3,4,3',4'-tetracarboxylic dianhydride (HBPDA), CAS number 122640-83-9, 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.

HBPDA based polyimides are solution-processable, owing to the bicyclohexyl moiety. The polyimides are biodegradable, exhibiting 90% weight-average molecular weight changed after 49 days of degradation by porcine pancreatic lipase.
