    Application
    2,2'-Bis(trifluoromethyl)benzidine is utilized to produce a high-strength, flexible, and transparent polyimide material. This fluorinated benzidine derivative, featuring two trifluoromethyl groups, serves as a crucial component in the creation of rigid and aromatic polyimides. It plays a significant role in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) that boast high specific surface areas. Additionally, 2,2'-Bis(trifluoromethyl)benzidine is employed to fabricate UV-resistant and colorless polyimide thin films, essential for optoelectronic applications. The electron-withdrawing nature of the fluoromethyl groups significantly reduces electron dispersion within the polymer's π-orbitals, enhancing transparency when compared to polyimides with methyl substituents. These properties make the polyimide ideal for encapsulating solar cells, particularly when used in conjunction with MOF-based cluster light diffusers.
