Asymmetrically substituted ferrocene derivatives showing redox switching of optical properties
The electrochemical and spectroelectrochemical behaviors of three ferrocene derivatives, (1) (C18H37)2NC6H4CHCHFcCH2OH, (2) (C18H37)2NC6H4CHCHFcCHO, (3) (C18H37)2NC6H4CHCHFcCHC(CN)2, were studied and analyzed on basis of frontier orbital interactions. It was shown that all the three derivatives show two oxidation steps. The first oxidized states of 1 and 2 are stable and show strong LMCT (ligand-to-metal charge transfer) bands. This suggests that they may serve as redox switching of optical properties. In contrast, the first oxidized state of 3 becomes unstable due to strong electron-withdrawing effect of the acceptor substitute.
