We report novel pseudorotaxanes based on the complexation between a pillar[4]arene[1]quinone and 1,10-dibromodecane. The complexation is found to have a 1:1 host–guest complexation stoichiometry in chloroform but a 2:1 host–guest complexation stoichiometry in the solid state. From single crystal X-ray diffraction, the linear guest molecules thread into cyclic pillar[4]arene[1]quinone host molecules in the solid state, stabilized by CH∙∙∙π interactions and hydrogen bonds.

Keywords: pseudorotaxanes; host-guest chemistry; pillararenes; pillar[4]arene[1]quinones; supramolecular chemistry
