[Uses]

1,3-Bis(4'-aminophenoxyl)benzene(2479-46-1) be used for the preparation of a polyimide material.
[Application]

4,4'-(1,3-Phenylenedioxy)dianiline (TPE-R,2479-46-1) is a phenyl ether derivative with two anilines in the terminal closure. It has the following applications:
(1) TPE-R with BPDA and BPDA can be used to prepare a series of polyimide oligomer (Oligo-PI) resins with controlled molecular weights through polymerisation reactions. Oligo-PI resins have an asymmetric and amorphous structure, which allows for better processing of composite materials.
(2) TPE-R copolymerised with other monomers (e.g. PEG) for the manufacture of fuel cell membranes with high ionic conductivity (210 mS/cm) and sufficient thermal stability (up to 140 °C).
(3) Polyimide composites prepared from TPE-R and titanate nanotubes can be used for electromagnetic shielding at microwave frequencies.
(4) TPE-R as an aromatic ligand can be crystallised with a variety of transition metals to form 0D, 1D and 2D coordination metal polymers, which can be used for sensing nitroaromatic compounds.
(5) TPE-R reacts with polydimethylsiloxanes with varying degrees of chloromethyl side functionalisation to form sec-amides and undergo cross-linking to form two networks, a siloxane-organic network and a silica network.
