Overview
Related Products

1,4-Bis(4-aminophenoxy)benzene (TPE-Q), CAS number 3491-12-1, is a diamino-building block with a phenyl ether core. 1,4-Bis(4-aminophenoxy)benzene is commonly used as a monomer for synthesizing polyimides with carboxylic acid dianhydrides. These polyimides are known for withstanding high temperatures. For instance, it is used as an ultra-thin flexible substrate for annealing MoS₂ up to 500°C and the integrated devices are applied for biopotential sensors. 1,4-Bis(4-aminophenoxy)benzene has a phenyl ether moiety (3 benzene rings linked by 2 oxygens in para-position), an electron donating group which is desired for designing intra-/intermolecular charge transfer complexes.

TPE-Q is synthesised for dielectrics which present Weibull breakdown strength of 440-540 MV/m and dielectric permittivity of 3.52-3.85. The polyimides made from TPE-Q, along with boron nitrite form high thermal conductive composite materials (2.75 W/m⋅K).
