Specifications | MSDS | Literature and Reviews
4,4'-(1,3-Phenylenedioxy)dianiline (TPE-R), CAS number 2479-46-1, a phenyl ether derivative end-capped with two anilines, is a precursor for the synthesis of high thermal resistant polyimides used as fire retardants. TPE-R can also be co-polymerized with other monomers, such as PEG, to manufacture fuel cells membranes with high ionic conductivity (210 mS/cm) and sufficient thermal stability (up to 140 °C). The polyimides composites based on 4,4'-(1,3-phenylenedioxy)dianiline and titanate nanotubes are applied in electromagnetic shielding at microwave frequencies.
By having two amines, TPE-R coordinates to metal centres forming 0D, 1D and 2D metal organic complexes that are used for sensing nitroaromatic compounds.
