摘要：
Two pillar[5]arene-based mechanically selflocked molecules (MSMs) were constructed successfully. In the crystal, two enantiomers of MSM 1 were observed in pairs, and packed alternately linked by anti-syn urea groups. Conformer inversions of these two MSMs were also investigated in solvent with gradually changed polarities, and by adding 1,4-dicyanobutane (G) as a competitive guest. (C) 2016 Elsevier Ltd.
