“…In step 3, protic solvents [ 1,[22][23][24][25] (mainly water) as well as acetonitrile [ 22 ] have been used as electrolytes for the electrosynthesis of PPy and PEDOT derivatives. For PPy, the use of an acetonitrile-based electrolyte was reported to yield more compact fi lms, with superior electron transfer characteristics and conductivities, presumably owing to the growing hydrophobicity of the chains during electropolymerization.…”

wileyonlinelibrary.comThe ideal mesoporous morphology should also exhibit interconnected pores of constant diameter for an optimized accessibility to the interfacial surface.The double-gyroid (DG) morphology with cubic 3 Ia d symmetry fulfi ls these criteria. It is a 3D continuous equilibrium structure arising from the self-assembly of strongly segregated diblock copolymers, [ 12,13 ] which comprises two interwoven single-gyroid networks with I 4 1 32 symmetry. These networks are related by inversion and are separated by a so-called matrix phase. A signifi cant advantage of the DG structure is the self-supporting nature of all constituent phases, which facilitates the synthesis of free-standing networks and thus greatly increases the number of possible fabrication pathways. Moreover, the pores as well as the surrounding struts are uniformly sized and well-ordered, ensuring interconnectivity of both networks across macroscopic dimensions.The replication of 3D nanonetwork morphologies into functional materials separates the optimization of a self-assembled template (such as a DG morphology) from the synthesis of the functional material that fi lls the template. While well established for metals [ 14 ] and metal-oxides, [ 15 ] it is also promising for the nanostructured synthesis of intractable organic materials. The replication of self-assembled templates is particularly interesting for conjugated polymers, the synthesis of which does not allow a precise control over their 3D morphology. Compared to inorganic templates, which require corrosive media for their chemical degradation, [ 16 ] soft organic templates offer the possibility of a mild template removal by dissolution. Recently, Cho et al. have demonstrated the microemulsion synthesis of conducting poly(3,4-ethylenedioxythiophene) gels with a DG morphology. [ 17 ] Retrieving a mesoporous aerogel from this precursor for application in functional devices is however virtually impossible because the gel itself is unstable and undergoes a transition from the gyroidal to the lamellar phase at 30 °C. In contrast, replicating mesoporous, DG-structured polymer templates into conjugated polymers may afford denser and therefore more stable functional materials.Compared to the replication of inorganic materials, template-assisted polymer synthesis presents many challenges, as it requires a complex multistep wet-chemical process involving several orthogonal solvents that are highly specifi c to either the template or the synthesized replica. Furthermore, synthesis reactions have to be chosen so that the template remains inert. The following requirements are essential:First, to form the mesoporous polymeric template, one of the copolymer blocks must be removed without affecting the 3D Nanostructured Conjugated Polymers for Optical ApplicationsRaphael Dehmel , Alexandre Nicolas , Maik R.

“…PEDOT can be doped with many anions, including macromolecular polyanions such as poly(styrene sulfonate) (PSS). Previous studies have shown that PEDOT is highly insoluble in most solvents, it is electroactive in aqueous solutions [17][18][19], and exhibits a relatively high conductivity. On the basis of these results studies have been performed to investigate the electrochemistry of PEDOT in more detail by using voltammetric techniques (in most cases cyclic voltammetry).…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractDeep eutectic solvents are evaluated as media for the electropolymerisation of 3,4-ethylenedioxythiophene (EDOT) for the first time. PEDOT modified glassy carbon electrodes (GCE) were characterised by cyclic voltammetry, electrochemical impedance spectroscopy and scanning electron microscopy. PEDOT modified GCEs prepared from choline chloride-urea (reline) and choline chloride -ethylene glycol (ethaline) exhibited interesting electrocatalytic and morphological characteristics. Fixed potential sensing of ascorbate at 0.0 V showed a greater electrocatalytic effect, significantly higher sensitivity and lower detection limit than at hitherto reported PEDOT modified electrodes.
