| Abstract: | Four diferrocenyl compounds: FcC(CH3)2Fc (1), Fc(CH3)C(C2H5)Fc (2), Fc(CH3)C(C3H7)Fc (3), and Fc(CH3)C(C6H5)Fc (4) were synthesized and characterized by NMR, FT-IR, MS, and elemental analysis. The molecular structures were determined by using X-ray single crystal diffraction. The electrochemical interactions between two ferrocenyl units in these compounds were investigated by cyclic voltammetry and theoretical calculation. The electron density of bridging carbon was a key factor for the separation of two ferrocenyl units. |
