A class of fluorinated phenylethynylaniline compounds is disclosed, said compounds having a use as capping reagents in high temperature stable polyimides or other polymers having a functionality which can undergo reaction with the amine to form a stable adduct. The diamine compounds of the invention are useful as step-growth monomers in the preparation of polymers containing reactive acetylene groups in the polymer backbone.
