Compound are described comprising a perfluorinated group bonded to at least one terminal photoinitiator group with an organic linking group comprising at least one amide moiety. The compound typically comprises the (e.g. Michael addition) reaction product of i) a compound comprising an acryl group and a photoinitiator group; and ii) an amino functional perfluorinated compound. Also described is a composition comprising at least one free-radically polymerizable (e.g. fluorinated) monomer, oligomer, or combination thereof; and the described fluorinated photoinitiator compound and methods.
