Cyclodextrin based polymers, methods, compositions and applications thereof

A polymer comprising the following structure:

• wherein:
• CD is a cyclodextrin moiety;
• L is a linker moiety having the structure:
• wherein:
• Ar1 and Ar2 are each independently a 5- or 6-membered heteroaryl comprising 1, 2, 3 or 4 heteroatoms individually selected from N, O, and S, wherein Ar1 and Ar2 are optionally substituted with R3;
• each Y is independently O, S, or NR4;
• m and p are each independently an integer from 1 to 10;
• R1 and R2 are each independently R4, OR4, S, or R1 and R2 together form a double bonded O, S, or NR4;
• R3 is selected from C1-C3 alkyl, C1-C3 alkyl sulphide, hydrazine, amine and halogen;
• R4 is H or a saturated or unsaturated C1-C10 linear alkyl, saturated or unsaturated C1-C10 branched alkyl, or saturated or unsaturated C1-C10 cycloalkyl, each of which is optionally substituted;
• and
• n is from 4 to 1000.
