The new ferrocene based receptors N-[4-ferrocenyl-2-methyl-4-oxobut-1-enyl] -N′-phenylthiourea (1), N-[4-ferrocenyl-2-methyl-4-oxobut-1-enyl]- N′-[4-nitrophenyl]thiourea (2) were synthesized and characterized. Fluorescence titrations of receptors 1 and 2 with various transition metal ions showed selective response to Cu2+ ions and the emission intensities quenched significantly. Electrochemical titrations with anions revealed that receptors 1 and 2 sensed the F- anion in high selectivity with a cathodic shift of 100 mV.
