Two new fluorinated diamine monomers, 3,3-diamino-5,5-bis(trifluoromethyl)biphenyl and 3,3 -diamino-6,6-bis(trifluoromethoxy)biphenyl, as well as a known nonfluorinated analog, 3,3 -diaminobiphenyl, were synthesized. Reaction of these diamines with rigid, highly rod-like dianhydrides produced poly(a
