Gel-Phase MAS NMR Spectroscopy of a Polymer-Supported Pseudorotaxane and Rotaxane: Receptor Binding to an "Inert" Polyethylene Glycol Spacer

A tricyclic polyamide receptor threads onto the polyethylene glycol chain of a carbohydrate‐attached resin, as shown by gel‐phase MAS NMR spectroscopy. This observation led to syntheses of a polymer‐supported pseudorotaxane and a porphyrin‐stoppered rotaxane (see picture).
