Abstract

Abstract: A series of thiourea-functionalised pillar[5]arene derivatives3 n m were constructed from a series of mono-amide-functionalised pillar[5]arenes2 n . The formation of their free forms or (pseudo)[1]rotaxane structures were controlled by their axle lengths or solvents, which were investigated by 1 H NMR spectroscopy. Some of (pseudo)[1]rotaxane structures were also supported by their single-crystal structures. Abstract :
