• wherein n is 1-2, and each occurrence of Rf1 and Rf2 is:
• (i) independently a linear or branched perfluoroalkyl group having 1-8 carbon and optionally comprises one or more catenated heteroatoms;
• or
• (ii) bonded together to form a ring structure having 4-8 carbon atoms and optionally comprises one or more catenated heteroatoms;
• and
• Rfh is, when n=1, a substituted or unsubstituted, monovalent, hydrocarbon group having 1-12 carbon atoms optionally comprising one or more catenary heteroatoms and, when n=2, a substituted or unsubstituted, divalent, hydrocarbon group having 1-12 carbon atoms optionally comprising one or more catenary heteroatoms.
