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: | 1369-9261 1144-0546 |
