derivatives, which have an adamantyl and methyl end group, respectively, formed self-inclusion complexes by threading of the arm moiety with a conformational conversion of altrose from (1)C(4) form to (4)C(1) form. Flexibility of the altro-alpha-CD cavity resulted in an induced fit (from (1)C(4) to (4)C(1)) to the arm moiety, and introducing a bulky end group allowed the stability of this pseudo[1]rotaxane
