摘　　要：设计合成了三种具有推拉电子取代基的二茂铁衍生物D-Fc-R(1),D-Fc-A_1(2),D-Fc-A_2(3)[D:(C_(18)H_(37))_2N-C_6H_4 CH=CH,R:CH_2OH,A_1:CHO,A_2:CH=C(CN)_2],并对其循环伏安及光谱电化学行为进行了研究.三种衍生物均出现两个氧化还原电对,1的两个电对均可逆.单扫第一电对,2的第一电对是可逆,3的第一电对是准可逆.D-Fc^+-R在613nm,D-Fc^+-A_1在705nm有强LMCT带,具有良好的光学特性氧化还原开关效应.Three ferrocene derivatives,D - Fc - R(1) ,D - Fc - A1 (2)and D - Fc - A2(3) [D: (C18H37)2N-C6H4-CH==CH,R: CH2OH,A1:CHO,A2:CH=C(CN)2],were designed and synthesized,and their electrochemical and spectroelectrochemical behaviors were studied. All these compounds show two redox processes. Both of the redox processes for 1 are reversible. The first wave of 2 is reversible and that of 3 is quasi - reversible when the electrode potential is scanned only in narrow range of the first wave.D- Fc+ - R and D- Fc+ - A1 show strong LMCT bands at 613 and 705 nm respectively,suggesting that they might be good at redox switching of optical properties.
