A　novel　monomer　called　1,1′-ferrocenediacyl　anilide　(FcA)　was　synthesized　from　ferrocene　(Fc).　Copolymerization　was　carried　out　between　FcA　and　aniline　(ANI)　by　an　electrochemical　method.　The　novel　monomer　and　copolymer　were　characterized　with　1H-NMR,　Fourier　transform　infrared　(FTIR)　spectroscopy,　and　ultraviolet-visible　(UV-vis)　spectroscopy.　The　hydrogen　protons　of　the　benzene　ring　were　moved　to　a　low　field　in　1H-NMR,　and　the　absorption　band　of　N£Q£N　(where　Q　is　the　quinoid　ring)　appeared　in　the　FTIR　spectrum　of　the　polymer.　The　peaks　of　both　Fc　and　the　π-π∗　electronic　transition　in　the　UV-vis　spectra　were　redshifted.　The　results　indicate　that　the　copolymer　mainly　existed　as　a　highly　delocalized　conjugated　system.　X-ray　diffraction　analysis　established　further　proof,　and　the　process　of　electrochemical　deposition　was　observed　by　scanning　electron　microscopy.　The　optimal　synthesis　conditions　of　the　copolymer　were　determined　through　changes　in　the　monomer　molar　ratios　and　the　scan　rate.　The　ideal　performance　of　the　copolymer　was　gained　when　the　monomer　molar　ratio　between　FcA　and　ANI　was　1:4　and　the　scan　rate　was　50　mV/s.　Furthermore,　the　electrochemical　performances　were　tested　in　detail　by　cyclic　voltammetry,　galvanostatic　charge-discharge　testing,　and　electrochemical　impedance　spectroscopy.　The　results　show　that　the　specific　capacitance　of　poly(1,1′-ferrocenediacyl　anilide-co-aniline)　increased　up　to　433.1　F/g　at　0.5　A/g,　the　diffusion　resistance　was　very　small,　and　the　durability　was　good　enough.　©　2015　Wiley　Periodicals,　Inc.
