Título: | Unprecedented 1,3-diaza[3]ferrocenophane scaffold as molecular probe for anions |
Autor: | Sola, A.; Orenes, R.A.; García, M. A.; Claramunt, Rosa M.; Alkorta, Ibon CSIC ORCID ; Elguero, José CSIC ORCID; Tarraga, Alberto | Fecha de publicación: | 2011 | Editor: | American Chemical Society | Citación: | Inorganic Chemistry 50: 4212- 4220 (2011) | Resumen: | The guanidine unit in the guise of 2-aminoimidazole in the new structural motif 2-arylamino-1,3-diaza[3]ferrocenophane 4 acts as a binding site for anions. The electrochemical behavior of this compound has been studied by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) and was found to exhibit a quasi reversible oxidation peak, associated to the Fe(II)/Fe(III) redox couple (Ep = 440 mV), and a non-reversible oxidation wave (Ep = 817 mV), probably associated to the oxidation of the C - N unit present in the guanidine bridge. Recognition of AcO-, PhCO2 -, F -, Cl-, and Br- anions by the free receptor and the less basic anions Br-, Cl-, and NO3 - by its monoprotonated form takes place by unusual redox-ratiometric measurements and spectroscopic (1H NMR and UV-vis) changes. © 2011 American Chemical Society. | Versión del editor: | http://dx.doi.org/10.1021/ic102314r | URI: | http://hdl.handle.net/10261/64516 | DOI: | 10.1021/ic102314r | Identificadores: | doi: 10.1021/ic102314r issn: 0020-1669 e-issn: 1520-510X |
