4,4'-Bis(4-aminophenoxy)biphenyl (BAPB) CAS 13080-85-8

A biphenyl ether diamine building block

As the intermediate for the preparation of polyimides in application of biomaterials, fuel cells, COFs and aerogels

Overview
Related Products

4,4'-Bis(4-aminophenoxy)biphenyl (BAPB), CAS number 13080-85-8, is a biphenyl derivative capped with two aminophenoxy groups at para-positions. 4,4'-Bis(4-aminophenoxy)biphenyl has a rigid biphenyl core and flexible phenyl ether bridges, thus the acquired polyimide aerogels (with density of 0.089 g/cm³) have fully bendable flexibility and high compression (E = 1.9 MPa). Showing excellent biocompatibility with human dermal fibroblasts and osteosarcoma cells, these polyimides are promising to use as coatings for biomedical devices and filaments for 3D printed implants.

With two amines, BAPB can be crosslinked with aldehydes to form covalent organic frameworks for sensing nitro-substituted aromatic compounds via photo-induced charge transfer mechanism.
