4,4'-Bis(3-aminophenoxy)biphenyl (43BAPOBP) CAS 105112-76-3

A diphenylamine with a biphenyl esters linker

As the intermediate for polyimides and imine synthesis in application of high performance polymers and sensors

Overview
Related Products

4,4'-Bis(3-aminophenoxy)biphenyl (43BAPOBP), CAS number 105112-76-3, has a biphenyl linker capped with two 3-aminophenoxy groups. 4,4'-Bis(3-aminophenoxy)biphenyl is typically use as a precursor for polyimides which have high chemical and thermal resistance. The polyimides are ideal for polymer matrices due to its high miscibility induced by intermolecular charge transfer. A shape memory film fabricated from the polyimides can recover to its original flat shape from temporary spiral shape on hot plate set at 240 °C. This is promising in the field of thermal actuators.

43BAPOBP can reacts with aldehyde to form imines. A fluorescence thin film developed from the imines has the ability to detect (sensitivity of 150 ppb – 1.5 ppm) and remove hydrogen chloride (187.5 w/w%) and ammonia (37.5 w/w%).
