The present invention relates to bisphenyl-2,3,5,6-tetrafluoro-4-trifluoromethylphenylphosphine oxide compounds and synthesis thereof, more particularly to novel bisphenyl-2,3,5,6-tetrafluoro-4-trifluoromethylphenylphosphine oxide compounds having both a perfluorinated benzene substituent and a phosphine oxide moiety. Compounds of the invention can be useful as a monomer for preparing polyimides having a low dielectric constant and a superior adhesion while maintaining the superior thermal and mechanical properties of polyimides themselves, and their synthesis thereof.
