|Title:||Thermodynamically self-assembling porphyrin-stoppered rotaxanes||Contributor(s):||Gunter, MJ (author); Bampos, N (author); Johnstone, KD (author); Sanders, JKM (author)||Publication Date:||2001||DOI:||10.1039/b006911f||Handle Link:||https://hdl.handle.net/1959.11/150||Abstract:||A variety of porphyrin-stoppered rotaxanes has been assembled under conditions of thermodynamic reversibility by judicious choice of components and temperatures. An admixture of a thread unit comprising a central naphthodiimide with terminal pyridines (2a), a ring unit dinaphtho-38-crown-10 (1) and either ZnII (3a), RuII (CO) (3b) or RhIII I (3c) as stoppers was shown to form an equilibrating mixture of pseudorotaxanes and the porphyrin-stoppered rotaxanes. The intact rotaxane could be crystallised from solution and chromatographed at low temperatures; at higher temperatures only a mixture of the components separated on chromatography. 1H NMR revealed NOE correlations between all three components for the rotaxane, and exchange peaks for related free and complexed species.||Publication Type:||Journal Article||Source of Publication:||New Journal of Chemistry, v.25, p. 166-173||Publisher:||Royal Society of Chemistry||Place of Publication:||United Kingdom||ISSN:||1144-0546||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: 129
