A fluorinated biphenyl diamine

As an intermediate for polyimides synthesis in application of high-performance polymers, flexible displays, and gas permeable membranes

Overview
Related Products

N,N'-(2,2'-bis(trifluoromethyl)-[1,1'-biphenyl]-4,4'-diyl)bis(4-aminobenzamide), CAS number 1449757-11-2, commonly known as AB-TFMB, has two anilines connecting to a trifluoromethyl biphenyl core through two carboxamides. AB-TFMB is used to synthesize polyimides with high transparency and low linear coefficient of thermal expansion (CTE) which are ideal for flexible displays. The transparency is brought by the trifluoromethyl substituents hindering the intermolecular charge transfer. The low CTE (4.2 ppm/K) is achieved by the linear and rigid structure of AB-TFMB.

The AB-TFMB based polyimides are also gas permeable with O₂-transmission rate up to 2313 cm³/m²/day at 23 °C and 1.01 bar.
