Ferrocenyl dithiophosphonate functionalized inorganic–organic hybrid conductive polymer with green color in neutral state

• A novel metal containing conducting polymer was synthesized.
• Electrochemical properties were investigated.
• Neutral state color of the polymer was in green color.

We report the synthesis and the characterization of the first electroactive ferrocenyl dithiophosphonate functionalized inorganic–organic hybrid conductive polymer. Electropolymerization was realized in boron trifluoride diethyl etherate (BFEE) with an applied potential of 1.5 V. Surface morphological, spectroelectrochemical, colorimetric and redox properties of polymer were investigated. Spectroelectrochemical and colorimetry studies have shown that ThFc has green color in neutral state.The reaction of the ferrocenyl dithiophosphonate and nickel(II) acetate gave rise to square-planar nickel(II)complex (ThFc–Ni). ThFc–Ni complex copolymerize with thiophene and spectroelectrochemical properties of copolymer were also investigated.
