概要 End-capping of permethylated α-cyclodextrin (PMCD)- poly(tetrahydrofuran) pseudorotaxane with 4-tritylphenyl isocyanate was carried out in the solid state in the presence of dibutyltin dilaurate to prevent dethreading. After 30 min. grinding of PMCD, poly(THF), and the catalyst, rotaxane with a high content of wheel component was isolated in 24% yield. Crosslinked rotaxane network (topol. gel) was produced by crosslinking monohydroxycyclodextrin-based polyrotaxane with 4,4'-diphenylmethane diisocyanate.
