The structure of 1,3-Bis(4-aminophenoxy)benzene contains two ether bond units and two reactive amino units, which have high chemical reactivity.The amino unit in the structure of TPE-R is strongly nucleophilic, and it can be condensed with common electrophilic reagents, for example, there is a report that it can be condensed with ethyl isothiocyanato-carboxylate to obtain the corresponding thiourea derivative. It can condense with common electrophilic reagents.
1,3-Bis(4-aminophenoxy)benzene is a diamine monomer containing two ether bonds and three benzene rings, and the interstitial substitution of the ether bond and the chain structure make the molecular chain less rigid and more flexible. This monomer is not only an important raw material for the preparation of homopolymerization or copolymerization type PI, but also can be used for the toughening modification of bismaleimide (BMI).
Its aminophenoxy group can participate in redox reactions, form complexes with metal ions, or undergo coupling reactions with other compounds. These properties make it potentially useful in electronic and optoelectronic devices, fluorescent displays, dye-sensitized solar cells, and so on.
In addition, TPE-R is an important intermediate with a wide range of applications in the fields of dyes, fluorescent dyes, polymers and photosensitive materials.
