A shift of up to 9 ppm in the 19 F NMR resonance of 1 is observed on complexation of metal ions. This property makes these compounds attractive as sensors for metal ions. The mode of coordination (σ bonding to the fluorine atom or η 2 coordination to the CF bond) in this type of system is also of interest.
