Abstract:
1. A monomer of formula (I): wherein: W is (CR Z is a zwitterionic group selected from the group consisting of (IIA), (IIB), (IIC), (IID) and (IIE), wherein group (IIA) has the formula: wherein each R group (IIB) has the formula: wherein each R group (IIC) has the formula: wherein each R group (IID) has the formula: wherein each R group (IIE) has the formula: wherein each R each R m is an integer from 0 to 6; and X is NR where R 2 , Y and the N atom to which they are bonded taken together form a 5 to 7 membered heterocyclic ring, wherein the heterocyclic ring may be optionally substituted with one or more R N , wherein each R N is independently selected from the group consisting of —H, —OH, —CN, —NO 2 , —CF 3 , —OCF 3 , —CO 2 H, —NH 2 , C 1 -C 10 alkyl, C 2 -C 10 alkenyl, C 2 -C 10 alkynyl, —O(C)—(C 1 -C 10 alkyl), —O(C 2 -C 10 alkenyl), —O(C 2 -C 10 alkynyl), halogen, —C(O)H, —C(O)—(C 1 -C 10 alkyl), —C(O)—O(C 1 -C 10 alkyl), —NH(C 1 -C 10 alkyl), —N(C 1 -C 10 alkyl) 2 , —C(O)—NH(C 1 -C 10 alkyl), —C(O)—N(C 1 -C 10 alkyl) 2 , —NH—C(O)—(C 1 -C 10 alkyl), —NH(C 1 -C 10 alkyl)-C(O)—(C 1 -C 10 alkyl), —NH—S(O) 2 —(C 1 -C 10 alkyl), —NH—(C 1 -C 10 alkyl)-S(O) 2 —(C 1 -C 10 alkyl), —(C 0 -C 10 )—SH, —S(O)—(C 1 -C 10 alkyl), —S(O) 2 —(C 1 -C 10 alkyl), —S(O) 2 —NH 2 , —S(O) 2 —NH—(C 1 -C 10 alkyl), —S(O) 2 —N(C 1 -C 10 alkyl) 2 and ═O; n is an integer from 0 to 6; or X is NR Y is —C(O)O— or —C(O)N(R n is 0; or X is O; Y is —C(=V)A-; where V is S or O; and A is selected from NR R n is 0.
