“…Structural defects in the conjugated backbone of polyfuran can be revealed by IR spectroscopy. 32 Previously reported polyfurans showed defects, such as ring-opening and β-coupling, which were observed by stretching vibrational modes of the aliphatic C–H bond (∼2900 cm –1 ), carbonyl C O bond (∼1720 cm –1 ), and O–H bond (∼3500 cm –1 ). 10b , 11a – c The measured ATR-FTIR spectra of P1 and P3 films on Pt-foil ( Fig.…”

“…FT-IR and Raman spectroscopy verifies that the polymer chain obtained is mainly conjugated, as is the PFu film synthesized by electrochemical reduction of 2,5-dibromofuran using Ni(bipy) 3 2+ as catalyst, 5 and much better than the PFu film electropolymerized in acetonitrile at 2.1-2.3V vs SCE using NaClO 4 as the electrolyte. 7,8 The obtained PFu film shows fairly good electrochemical reversibility and stability in organic solvents, while it undergoes irreversible oxidation in aqueous solution. On the other hand, the undoped state of PFu is very stable in air, similar to that of the undoped polythiophene.…”

Low Potential Electrochemical Synthesis of Polyfuran and Characterization of the Obtained Free-Standing Film

A free-standing polyfuran (PFu) film has been successfully synthesized by electrochemical polymerization of furan at low potential (1.2 V vs Ag/AgCl) in a binary solvent system consisting of boron trifluoride-ethyl ether (BFEE) and additional ethyl ether (EE). The obtained polymer contains much less ring-opened component and shows higher conductivity than that prepared by chemical method or by electropolymerization in other solvent systems. Its electric conductivity is as high as 10 -2 S cm -1 both in its electrochemically doped state and chemically doped state with I 2 . Moreover, the obtained free-standing film shows good mechanical properties, which makes itself a powerful competitor to other conducting polymers. The orientation of PFu deposited on Au and stainless steel electrode was investigated by surface enhanced Raman spectra (SERS) and reflection-absorption infrared spectra (RA-IR) techniques. The furan ring in the polymer chain is inclined to be arranged parallel to the metal surface at the early stage of deposition.

“…Deconvolution of the transients was carried out to establish the NGM of each deposit using equations derived for the modeling of metal electrodeposits. This method has been described and validated in previous works reported elsewhere by our research group [5,16], and subsequently by other groups [17][18][19].…”
