摘要：

A self-assembling molecular capsule based on electrostatic interaction has been designed and its structure is investigated by dynamic H-1 NMR. The hydrodynamic description resulting from relaxation and PGSE H-1 NMR experiments indicates that association between oppositely charged hydrophilic beta-cyclodextrin derivatives in 50 mM KCl aqueous solution corresponds to dimerization with an interdistance between interacting units lying in the 0.4-1.1 nm range with a maximal probability at 0.6 nm.
