Description and Uses

1,4-Bis(4-amino-2-trifluoromethylphenoxy)benzene is an aminophenyl ether with two trifluoromethyl groups in the amine interstitial position is a precursor for the synthesis of polyimides, with high heat resistance (5% heat loss at 525°C), extraordinary mechanical properties (tensile strength >60 MPa, Young's modulus >4 GPa) and excellent insulating properties (breakdown strength >358 kV/mm). As a result, these polyimides can be used as insulating materials with low energy consumption. The spatial effect of the trifluoromethyl group reduces intermolecular aggregation, leading to a low refractive index and high transparency to the polyimide. The polyimides derived from 1,4-Bis(4-amino-2-trifluoromethylphenoxy)benzene can be used as interlayers for current collectors in high energy lithium-ion batteries. This type of current collectors improves 16–26% specific energy and can self-extinguish fires under short circuits.

4,4'-[1,4-PHENYLENEBIS(OXY)]BIS[3-(TRIFLUOROMETHYL]BENZENAMINE can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development and chemical production processes.
