Description and Uses
2,2'-Bis(trifluoromethyl)benzidine (TFMB) is a fluorinated benzidine derivative with two trifluoromethyl substituents at the 2- and 2'-positions. 2,2'-Bis(trifluoromethyl)benzidine (TFMB) is a rigid and aromatic polyimide used in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) of high specific surface area.TFMB is also synthesised as UV-resistant and colourless polyimide thin films for optoelectronic applications. TFMB is also used to synthesise UV resistant and colourless polyimide films for optoelectronic applications. The two fluoromethyl groups have a strong electron-withdrawal effect, which reduces the electron dispersion in the π-orbitals of the fully conjugated polymer backbone. This effect results in a much higher transparency of the polyimide film compared to polyimide films containing methyl substituents. This polyimide can be used for the encapsulation of solar cells with MOFs cluster light diffusers.
2,2'-Bis(trifluoromethyl)benzidine is used for producing a high strength flexible transparent polyimide material.
