title: First fluorescent ferrocenyl compound as multiresponsive calcium-sensing device. NMR, electrochemical, and photophysical preliminary investigations in CH(3)CN.
abstract: A new ferrocene receptor binds a calcium guest via complex processes involving the whole unsaturated core of the ligand. Complexation induces significant changes in the ligand properties, as evidenced by the unprecedented cation sensing observed both by electrochemistry and fluorescence spectroscopy.
