[n]Pseudorotaxanes constructed by a bis(p-phenylene)-34-crown-10-based cryptand: different binding behaviors induced by minor structural changes of guests†
Abstract
Three pseudorotaxanes consisting of a bis(p-phenylene)-34-crown-10-based cryptand host and 1,2-bis(4-pyridinium)ethane/ethylene derivative guests were obtained. It was found that small structural changes on guests could have a big effect on the binding behaviors of host–guest complexes.
