文摘
Novel dynamic polyrotaxanes constructed from pillar[5]arenes as wheels and diamines as axles have been successfully synthesized in good yield using quadruple hydrogen bonding ureidopyrimidinone (UPy) motifs, which play a dual role as the end-capping and interlocking units. The present study is the first example of noncovalent bonded dynamic polyrotaxanes constructed by multiple hydrogen bonding interactions.
