Abstract

Compounds represented by formula (Rf-Q-X)s—Z. Each Rf is independently a partially fluorinated or fully fluorinated group selected from Rfa-(O)r—CHF—(CF2)n—; [Rfb-(O)tC(L)H—CF2—O]m—W—; CF3CFH—O—(CF2)p—; CF3—(O—CF2)z—; and CF3—O—(CF2)3—O—CF2—. Methods of reducing surface tension of a liquid, making foams, and treating a surface using the compounds are also disclosed.
