It has been disclosed for the first time that a cyclodextrin (CD) derivative is able to act as a macrocyclic monomer for ring‐opening polymerization to produce linear polyglucan. O ‐Permethylated α ‐, β ‐, and γ ‐CDs were found to be polymerizable with the aid of a cationic initiator, e.g., Et 3 O + PF 6 – in dichloromethane. Interestingly, the more strained monomer ( α ‐ > β ‐ > γ ‐CD) was less reactive, which is ascribable to the characteristic shape of the CD molecule.
