Partially fluorinated amino acid derivatives as gelling and surface active agents

A composition of formula (I)

• wherein A is independently selected from the group consisting of:
• hydrogen, C1-C5 straight and branched chain alkyl, phenyl, benzyl, and —C(O)—Y—Rf;
• Y is independently —O— or —NH—;
• Rf is a monovalent group selected from the group consisting of formulas (IIa), (IIb) (IIc) and (IId):
• Rf1 and Rf2 are C1-C6 linear or branched perfluoroalkyl;
• Rf3 is a C1 to C7 linear or branched perfluoroalkyl group, optionally interrupted by one, two or three ether oxygen atoms;
• u and t are independently integers of 1 to 10;
• q and r are independently integers of 1 to 3;
• n is an integer of 0 to 10;
• B is independently selected from the group consisting of:
• —O—, —NH—, and a covalent bond;
• P is selected from the group consisting of:
• (R1O)3Si— and CH2═C(R2)—CO2—;
• wherein R1 is a C1-C6 straight and branched chain alkyl;
• R2 is a hydrogen, F, Cl or —CH3;
• R is a monovalent, divalent, trivalent or tetravalent group having 1 to 60 carbon atoms;
• d is an integer of 0 or 1;
• and
• m is an integer of 1-4;
• with the provisos that m+d≦4;
• R has at least m+d carbon atoms with each valence residing on a different carbon atom;
• and
• when Y is —O—, Rf is selected from formulas (IIb), (IIc) or (IId).
