The binding of NH4+ to novel ferrocenyl aza crownethers 7 and 6, respectively, containing two and three ferrocene redox-active centres attached to amine functionalised di- and tri-aza crownethermacrocycles, results in large anodic shifts of the ferrocene/ferricinium redox couple, by up to 220 mV with 6.
