1. A rotaxane comprising a host molecule and a guest molecule, said host molecule being a cucurbit[n]uril (CB[n]), and said guest molecule having the general Formula I:
-
U—
B1-L1-[A]m-L2-B2—
Y
Formula Iwherein;
n is an integer that ranges from 5 to 20;
B1 and B2 are each independently an uncharged stopper moiety;
L1 and L2 are each independently an uncharged linking moiety or absent;
[A]m is a linear and rigid threading moiety having a neutral net charge at a pH that ranges from 6-8;
whereas A is selected from the group consisting of a 1,2-ethyn-di-yl, substituted or unsubstituted cyclobuta-1,3-diene-1,3-di-yl, substituted or unsubstituted pentalene-2,5-di-yl, substituted or unsubstituted pyrene-2,7-di-yl, C-substituted or unsubstituted pyridine-2,5-di-yl, C—
substituted or unsubstituted pyrimidine-2,5-di-yl, C-substituted or unsubstituted pyrazine-3,6-di-yl and 1,2,4,5-tetrazine-3,6-diyl, andm is an integer that ranges from 1 to 50; and
U and Y are each independently selected from the group consisting of an anchoring group, an effector moiety, a detectible moiety, a biomolecule, or absent.
