“…Under the conditions employed for these experiments, the pseudo-reference electrode had a potential of 25 -450 mV with respect to the ferricinium/ferrocene couple. All electrochemical experiments were performed using a PAR EG&G model 263A potentiostat in a three-compartment cell under an atmosphere of N 2 .…”

“…1 cm 2 ) electrode in degassed acetonitrile 25 (MeCN), containing electrolyte. In a typical experiment the electrode potential was cycled repetitively between -0.2 V and +1.2V at a scan rate of 50 mV s -1 until sufficient polymer was deposited on the electrode surface.…”

“…a halogen or other atom) with which to carry out comparison. In principle, comparative integration of the S(2p), C(1s) or O(1s) spectral regions for PEDOT can yield the required information, but in 25 practice the errors are large because these integral ratios are often distorted by small amounts of surface air-borne (adsorbed) contamination. Here we have taken an alternative approach: quantification has been achieved by iterative, numerical, fitting of the measured spectral data in the C(1s) 30 region with numerically-generated combinations of reference spectra for the individual homopolymers.…”

Here we have studied the electrocopolymerisation of binary mixtures of functionalised thiophenes in varying compositions and determined independently for each copolymer the spectroelectrochemical responses and the composition of the material using x-ray photoelectron 15 spectroscopy. We have observed strong correlations between the composition of the copolymer material and the composition of the binary solution from which the polymer was grown. In addition, we have shown that the spectroelectrochemical properties of the copolymers indicate the presence of random copolymer material where the λ Max values of the neutral, undoped, polymer scales with composition but also suggest that there may be small amounts of block copolymer or 20 phase-separated mixtures of the homopolymer components.

Copolymers of 3,4‐ethylenedioxythiophene and 3‐methylthiophene have been prepared by recurrent potential pulses using monomer mixtures with various concentration ratios, their properties being compared with those of the corresponding homopolymers. In addition, different technological applications have been tested for the generated copolymers. Results indicate that the properties of the copolymers are closer to those of poly(3,4‐ethylenedioxythiophene) than to those poly(3‐methylthiophene). Furthermore, the ability of the copolymers to store charge and to interact with plasmid DNA suggest that they are very promising materials.

The structural, electric and electronic properties of copolymers derived from mixtures of N‐methylpyrrole and 3,4‐ethylenedioxythiophene (EDOT) with various concentration ratios have been investigated and, additionally, compared with those of the corresponding homopolymers. The electropolymerization kinetics of all the generated copolymers and the homopolymers was examined in terms of current productivity using chronoamperometry. The chemical structure of the linkages between adjacent monomers and the microstructure of the chains were investigated using Fourier transform infrared spectroscopy and quantum mechanical calculations, respectively. The results indicate that the linkages between monomeric units formed during the anodic copolymerization are of the α–α type, while the microstructure of the copolymers depends on the EDOT content. Theoretical calculations were also used to examine the electronic properties of the systems under study, while the conductivity and the electrical stability were studied using the sheet‐resistance method. Interestingly, the electric properties are consistent with the random and block microstructures predicted for the copolymers with low and high EDOT content, respectively.
