Mpl. Werts et al., Towards mechanically linked polyrotaxanes by sequential deprotection-coupling steps of bifunctional rotaxanes, CHEM COMMUN, (7), 1999, pp. 623-624
The monomer rotaxane 13, bearing two protected functional groups, is used t
o obtain a dimer, following a new approach of sequential deprotection-coupl
ing steps which can lead to mechanically linked polyrotaxanes.
