Host guest complexation between an alkane functionalized with triazole moieties and three pillar[5]arenes was studied. Three pillar[5]arene-based [2]rotaxanes were constructed based on this new recognition motif. The sequence of the yields of these [2]rotaxanes was consistent with the order of association constants between the three corresponding and the alkane. H-1 NMR, electrospray ionization mass spectrometry,and NOESY NMR were employed to characterize these [2]rotaxanes. (C) 2012 Elsevier Ltd. All rights reserved.
