Threading/Folding Recognition Modes of Phosphodiesters by a p-Nitrophenylamide Cyclodextrin Derivative
A cyclodextrin derivative 1 possessing multiple p-nitrophenylamide groups, which is a strong hydrogen-bond donor, encapsulates phosphodiester anions in two recognition modes. One is the 'threading' mode, in which the phosphodiester passes through the cyclodextrin cavity. The other is the 'folding' mode, in which the included phosphodiester is bent inside the cyclodextrin cavity. The tendency between the two recognition modes depends on the substituents on the phosphodiesters.
