| Abstract: | A series of thiourea-functionalised pillar[5]arene derivatives 3nm were constructed from a series of mono-amide-functionalised pillar[5]arenes 2n. The formation of their free forms or (pseudo)[1]rotaxane structures were controlled by their axle lengths or solvents, which were investigated by 1H NMR spectroscopy. Some of (pseudo)[1]rotaxane structures were also supported by their single-crystal structures. |
