A [2]rota[2]catenane, constructed from a pillar[5]arene-crown ether fused double-cavity macrocycle: synthesis and structural characterization

A topologically novel [2]rota[2]catenane containing both a pillar[5]arene-imidazolium based [2]rotaxane subunit and a crown ether-tetracationic cyclophane based [2]catenane one was designed and constructed. The structure of the [2]rota[2]catenane was thoroughly characterized by NMR spectra, MS spect...

Zusammenfassung:A topologically novel [2]rota[2]catenane containing both a pillar[5]arene-imidazolium based [2]rotaxane subunit and a crown ether-tetracationic cyclophane based [2]catenane one was designed and constructed. The structure of the [2]rota[2]catenane was thoroughly characterized by NMR spectra, MS spectrometry and single crystal X-ray diffraction analysis.
