A. Tarraga et al., Synthesis and electrochemical properties of a new range of strained 2-aza-[3]ferrocenophanes, TETRAHEDR L, 42(51), 2001, pp. 8989-8992
The previously unreported 2-aza-[3]ferrocenophanes 3 and 4, prepared from a
preformed [5]ferrocenophane. act as electrochemical sensors either of Mg2, Zn2+ and Ni2- cations (free ligand): a new redox peak appears in the CV s
hifted 310-360 mV or hydrogensulfate anion (protonated ligand) via a signif
icant cathodic perturbation. (C) 2001 Elsevier Science Ltd. All rights rese
