“…Poly (3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS), one of the most successful conducting polymers commercially available in the form of aqueous dispersion as colloidal particles, has superior mechanical properties, thermal stability, and high conductivity, which provides potential applications to electrical and optical devices such as transparent electrodes for touch panels and flexible displays [1,2], capacitors [3], microfibers [4][5][6], Shottky diodes [7], field-effect transistors [8][9][10], and actuators [11][12][13]. The resistance of the conductive polymer is, however, too high to fabricate a large-area electronic circuit due to the low electrical conductivity of the commercially available pristine PEDOT/PSS [4,13].…”

Highly conductive films made of poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) were prepared by casting the PEDOT/PSS aqueous dispersion of colloidal particles containing ethylene glycol (EG). By addition of 3% of EG, the electrical conductivity was significantly increased from 3 to 430 S/cm. The EG was crucially important for (i) removal of the insulating PSS from the surface of the PEDOT/PSS particles, (ii) crystallization of PEDOT molecules, and (iii) aggregation of the particles, which improved both intra-and inter-particle transfer of charge carriers. A further increase of the EG concentration, however, decreased the conductivity, which was due to the morphological inhomogeneity by the phase segregation.

“…Therefore, the PEDOT/PSS colloidal gel particles can be shaped into various shapes such as thin coatings on various substrates [3,4], fibers [5,6], and freestanding thick films (quaternary structure) [7,8], which can be applied to printed organic electronics. Because of its high electrical conductivity, transparency, and thermal stability, the PEDOT/PSS has attracted considerable attention for transparent electrodes of flexible displays [9,10], touch panels [11,12], and solar cells [13] as an alternative of indium tin oxide (ITO) due to the drain problem of rare metals.…”

Poly(3,4ethylenedioxythiophene) doped with poly(4styrenesulfonate) (PEDOT/PSS) with various PSS composition ratios (α) was synthesized by oxidative polymerization and particle size distribution and zeta potential of the resulting colloidal gel particles were investigated by means of a dynamic light scattering technique. It was found that mean volume diameter of the PEDOT/PSS colloidal gel particles were 400600 nm at α = 1~6, which drastically decreased to ~10 nm at α = 8~15. On the other hand, zeta potential was about 80 mV regardless of the composition ratio. The electrical conductivity of the PEDOT/PSS cast film measured by a fourpoint method attained as high as 263 S/cm at α = 3.

“…Polythiophenes, especially their 3-alkyl substituted derivatives (P3ATs) form a practically important family of these materials [28][29][30][31][32], because they can be synthesized and processed easily, and their doped states are stable in air [1,4,6,31,[33][34][35][36][37][38][39][40][41].…”

A thermochemical investigation of singlet dication (bipolaron) structures in a set of 3-methyl-thiophene oligomers (up to the length of 24-mers) was carried out. Equlibrium structures and heats of formation were calculated with the semiempirical quantum chemical method RHF/PM3 for the doubly oxidized forms. All-cisoid planar structural variants of the form A n1 Q n2 A n3 were considered, where A and Q are thiophene monomer units in aromatic and quinoidal chain segments, respectively. The types of segments were determined from their bond-length pattern. At this level of theory, diverse structures combining both types of segments were found stable.The so-called "response equation based quantitative structure-property relationship" (REQ-QSPR) method, recently proposed by Fishtik et al. was used to perform and interpret regression data analysis. The REQ-based approach rationalizes mathematical treatment of stoichiometric equations. It provides a simple concept for breaking down a dataset for heat of formation into linear combination of terms that are easy to interpret in the framework of chemical groups. REQ-QSPR includes arbitrary structural descriptors rather than being restricted to using only the number of chemical constituents. Applied to our system, it is demonstrated that modelling nonlinear effects becomes possible as well. Supra-linear dependence of the energy with respect to the bipolaron localization length is indicated by REQ-QSPR, and detailed analysis suggests specific further calculations to carry out for improving the model.
