Pentakis(3,6-anhydro)-α-cyclodextrin and three regioisomers of tetrakis(3,6-anhydro)-α-cyclodextrin were synthesized from the corresponding 6-O-sulfonates to investigate the relationship among the molecular geometry, hydrophobicity-hydrophilicity balance, and inclusion behavior of CD. Each of the CD derivatives exhibited characteristic cation binding ability reflecting the unique molecular structure.
