each R 6c and R 6d is independently selected from hydrogen, halogen, —CN, —OR 9a , optionally substituted C 1 -C 4 alkyl, optionally substituted C 1 -C 4 fluoroalkyl, optionally substituted C 2 -C 6 alkenyl, —NR 3c R 3d , —S(═O) 2 O—, —S(═O) 2 OR 9a , —C(═O)O—, and —C(═O)OR 9a ;

X is —C(═O)—, —S(═O)—, or —S(═O) 2 —;

each R 9a , R 12a , R 12b , and R 12c is independently selected from hydrogen, optionally substituted C 1 -C 4 alkyl, and optionally substituted aryl;

t is an integer selected from 1, 2, 3, 4, or 5; and

p is an integer selected from 1, 2, 3, 4, or 5.

2. The compound of claim 1 , wherein each R 6c and R 6d is independently selected from hydrogen and —CH 3 .

3. The compound of claim 1 , wherein the zwitterionic monomer having the structure of formula (V) comprises sulfobetaine.

4. The compound of claim 1 , wherein the zwitterionic monomer having the structure of formula (V) is
