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.
本发明涉及双苯基-2,3,5,6-四氟-4-三氟甲基苯基氧化膦化合物及其合成,更具体地涉及具有全氟苯基取代基和膦氧基团的新型双苯基-2,3,5,6-四氟-4-三氟甲基苯基氧化膦化合物。本发明的化合物可用作制备具有低介电常数和优异附着性能的聚酰亚胺单体,同时保持聚酰亚胺本身的优异热力学和机械性能,以及其合成方法。
