Electrochemical and Fluorescent Properties of Ferrocenyl Chalcones Containing 1-Naphthalenyl Group: X-ray Crystal Structure of Fc-C(O)CH=CH-(1-Naph)

exhibit one reversible cycle for the redox of the ferrocenyl moiety at a lower potential, and one irreversible oxidation peak at the higher potential region. For Fc-d1Naph, the cyclic voltammogram is more featureless. Fluorescence properties for both compounds are active in polar solvents with λem = 500 nm (EtOH) and λem = 512 nm (MeOH) for Fc-1Naph and λem = 496 nm (EtOH) and λem = 508 nm (MeOH) for Fc-d1Naph. The intensity of Fc-d1Naph is more than twice than that of Fc-1Naph. The fluorescence properties for both compounds are inactive in the less polar solvents such as CH3CN, CH2Cl2 and CHCl3.
