REDOX SWITCHING EFFECT ON OPTICAL-PROPERT IES OF FERROCENE DERIVATIVES

Three ferrocene derivatives, D-Fc-R(1), D-Fc-A(1)(2) and D-Fc-A(2)(3) [D:(C18H37)(2)N-C6H4-CH=Ch, R:CH2OH, A(1):CHO, A(2):CH=C(CN)(2)], were designed and synthesized,and their electrochemical and spectroelectro chemical behaviors were studied. All these compounds show two redox pr ocesses. Both of the redox processes for 1 are reversible. The first w ave of 2 is reversible and that of 3 is quasi-reversible when the elec trode potential is scanned only in narrow range of the first wave. D-F c(+)-R and D-Fc(+)-A(1) show strong LMCT hands at 613 and 705 nm respe ctively, suggesting that they might be good at redox switching of opti cal properties.
