The cyclic voltammogram of 11、16、17 shows one successive reversible electron redox wave corresponding to the oxidation of the ferrocene moiety. In addition, the E1/2 wave is (7，0.36V，11，0.44V), (16，0.405V，17，0.549V), there exists some electronic communication between the two active centers through the azine bridige. We found substituent is electron-withdrawing groups. In the crystal structure , Fe → C average bond length (11 = 2.046 Å, 16 = 2.042 Å) , C = N bond length of about 1.27 Å, N-N bond length about 1.42 Å. In the optical, UV -Vis absorption spectroscopy, we observed that triarylamine at 254, 395 nm, anthracene at 254, 395 nm are typical of π → π * absorption, and we also observed that the greater the number of substituent, the more intensity of the absorption and the stronger the fluorescence intensity.
