One-pot synthesis of main chain-type polyrotaxane containing cyclodextrin wheels
Polyrotaxane possessing cyclodextrin wheels was prepared in one pot through the initial threading complexation of polytetrahydrofuran axle and a-cyclodextrin wheel followed by the end-capping reaction of the terminal amino groups of the axle with a bulky isocyanate in water.
