|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:||UK||ISSN:||1477-0520||Field of Research (FOR):||030302 Nanochemistry and Supramolecular Chemistry||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 493
