A patterning process comprises (a) providing at least one substrate having at least one major surface; (b) providing at least one patterning composition comprising at least one functionalizing molecule that is a perfluoropolyether organosulfur compound; (c) applying the patterning composition to the major surface of the substrate in a manner so as to form at least one functionalized region and at least one unfunctionalized region of the major surface; and (d) etching at least a portion of the unfunctionalized region.

A perfluoropolyether thiol compound comprises a perfluoropolyether segment, at least one mercapto group (—SH), and at least one intervening divalent carbonylimino moiety (—C(═O)—NR—, wherein R is hydrogen or alkyl). The compound can be produced, for example, by a ring-opening reaction of thiolactones with perfluoropolyether-substituted, primary or secondary amines. The compound can be used, for example, as a polymerization chain transfer agent, as an intermediate for the preparation of functional group-containing fluorochemical derivatives such as disulfides, and as a fluorinated surface treatment.

A method of modifying a surface of a hydrocarbon-bearing formation is disclosed. The method includes contacting the surface of the hydrocarbon-bearing formation with a fluorinated amine, and the surface of the hydrocarbon-bearing formation includes a carbonate. The method can typically include introducing a treatment composition comprising solvent and at least one of the fluorinated amine or a salt thereof into the carbonate hydrocarbon-bearing formation. Hydrocarbon-bearing formations treated according to the method are also disclosed. Certain fluorinated amines useful for treating carbonate hydrocarbon-bearing formations and methods of making them are also disclosed.
