Title: | Monitoring the thermodynamically-controlled formation of diimide-based resin-attached rotaxanes by gel-phase HR MAS ¹H NMR Spectroscopy | Contributor(s): | Mullen, Kathleen (author); Johnstone, Ken (author); Webb, Matthew (author); Bampos, Nick (author); Sanders, Jeremy K M (author); Gunter, Maxwell John (author) | Publication Date: | 2008 | DOI: | 10.1039/b716325h | Handle Link: | https://hdl.handle.net/1959.11/1351 | Abstract: | The thermodynamically controlled self-assembly of rotaxane and pseudorotaxane systems consisting of (i) a naphthodiimide thread unit terminated at one end with a pyridine ligand, and covalently linked at the other to a gel-phase polystyrene resin support, (ii) a dinaphtho-crown ether shuttle unit, and (iii) a ruthenium carbonyl metalloporphyrin stopper unit, is investigated by high resolution magic angle spinning proton (HR MAS ¹H)NMR spectroscopy. The effects of variable concentration of the solution-phase components, the tempurature, and added Li⁺ and Na⁺ ions are described, and the limitations of the technique are addressed. The dynamic behaviour is compared directly to the solution-phase analogues, where a bulky stopper group is substituted for the polystyrene resin bead. | Publication Type: | Journal Article | Source of Publication: | Organic & Biomolecular Chemistry, 6(2), p. 278-286 | Publisher: | Royal Society of Chemistry | Place of Publication: | United Kingdom | ISSN: | 1477-0539 1477-0520 |
