Abstract

Abstract: The synthesis and characterization of a new member of the pillar[5]arene family carrying a paramagnetic side‐arm based on the 2, 2, 6, 6‐tetramethylpiperidine N ‐oxide (TEMPO) moiety has been achieved by the Huisgen‐type CuAAC reaction. The possibility of exploiting the proposed pillar[5]arene as a host in paramagnetic rotaxane‐like structures was tested in the presence of charged guests and confirmed by NMR spectroscopy. Abstract : The first example of a paramagnetic pillar[5]arene is reported.
