TY - JOUR A1 - Sheng, Xinru A1 - Li, Errui A1 - Huang, Feihe T1 - Construction of pillar[4]arene[1]quinone/1,10-dibromodecane pseudorotaxanes in solution and the solid state JF - Beilstein Archives Y1 - 2020/// SN - M3 - doi:10.3762/bxiv.2020.109.v1 N2 - 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.
