Fluorinated compounds represented by formula Rf-Q-X-[Si(R) f (R 1 ) 3-f ] g . Each Rf is independently a partially fluorinated or fully fluorinated group selected from Rf a -(O) r -CHF-(CF 2 ) n -; [Rf b -(O) t -C(L)H-CF 2 -O] m -W-; CF 3 CFH-O-(CF 2 ) p -; CF 3 -(O-CF 2 ) z -; and CF 3 -O-(CF 2 ) 3 -O-CF 2 -. Methods of treating a surface or a hydrocarbon-bearing formation using the fluorinated compounds and treated articles and treated hydrocarbon-bearing formations are also disclosed. |
