Abstract
Provided are amphiphilic copolymers that include repeat units of formulas [Z]m and [P]n, wherein Z is a zwitterionic structural unit including at least one pendant heteroaromatic moiety, the heteroaromatic moiety containing a positively charged quaternary nitrogen atom (e.g., a pyridine ring), and wherein at least one negatively charged functional moiety is linked to the heteroaromatic moiety directly or through a linker, wherein the linker, where present, is an optionally substituted alkyl linker; P is a structural unit including a hydrophobic moiety, the hydrophobic moiety being a linear, branched, or cyclic fluorine-substituted C1-C20 moiety; m is an integer that is ≥1; and n is an integer that is ≥1.
Claims22
An amphiphilic copolymer comprising repeat units of formulas
- wherein
- Z is a zwitterionic structural unit comprising at least one pendant heteroaromatic moiety, wherein the heteroaromatic moiety comprises a positively charged quaternary nitrogen atom, and wherein at least one negatively charged functional moiety is linked to the heteroaromatic moiety directly or through a linker, wherein the linker, where present, is an optionally substituted alkylene linker;
- P is a structural unit comprising a hydrophobic moiety, said hydrophobic moiety being or comprising a linear, branched, or cyclic fluorine-substituted C1-C20 alkyl moiety;
- m is an integer that is ≥1;
- and
- n is an integer that is ≥1.
