Tuning of the electrochemical recognition of substrates as a function of the proton concentration in solution using pH-responsive redox-active receptor molecules

Reaction of ferrocene-1,1′-dicarbaldehyde and ethane-l,2-diamine yielded the Schiff-base derivative 2,5,19,22-tetraaza<6.6>(1,1′)ferrocenophane-1,5-diene, 1 the molecular structure of which has been determined by singlecrystal X-ray analysis.Hydrogenation of 1 with LiAIH4 resulted in the corresponding amine 2,5,19,22-tetraaza<6.6>(1,1′)ferrocenophane 2 which was characterised crystallographically.The protonation behaviour of 2 (denoted as L) and its complex formation with copper(II), nickel(II) and zinc(II) has been studied by potentiometric titrations in tetrahydrofuran-water (70:30 v/v) (0.1 mol dm-3 NBu4ClO4, 25 deg C).The complexes 3+, 2+, + and are formed.An electrochemical study of compound 2 has also been performed under the same conditions at which the potentiometry was carried out and the pKa values for the mixed-valence Fe(II)Fe(III) and oxidised Fe(III)Fe(III) species determined by fitting the curve of E1/2 versus pH.From those data the Pourbaix diagram of the redox-active 2 has been calculated.Compound 2 can be considered as a selective electrochemical sensor for copper(II).
