“…[ 80 ] The hydrophilic nature of PSS and the hydrophobic nature of PEDOT offer a means for selective de-doping of PSS through the use of hydrophilic solvents such as EG.

The rapid development of novel organic technologies has led to significant applications of the organic electronic devices such as light‐emitting diodes, solar cells, and field‐effect transistors. There is a great need for conducting polymers with high conductivity and transparency to act as the charge transport layer or electrical interconnect in organic devices. Poly(3,4‐ethylenedioxythiophene): poly(styrenesulfonic acid) (PEDOT:PSS), well‐known as the most remarkable conducting polymer, has this role owing to its good film‐forming properties, high transparency, tunable conductivity, and excellent thermal stability. In this Review, various of interesting physical and chemical approaches that can effectively improve the electrical conductivity of PEDOT:PSS are summarized, focusing especially on the mechanism of the conductivity enhancement as well as applications of PEDOT:PSS films. Prospects for future research efforts are also provided. It is expected that PEDOT:PSS films with high conductivity and transparency could be the focus of future organic electronic materials breakthroughs.

“…The dependence of conductance on the amount of DMSO is similar to that observed in the reported data. 8 However, contrary to the results from solvent vapor treatment, no enhancement in the conductivity of the films was observed on methanol addition in Table 1 Conductivity of PEDOT/PSS films after solvent vapor-treatment at 35℃ for 60 min. 4e The removal of the insulating PSS from the film, in addition to changes in morphology and conformation are proposed as the cause for the conductivity enhancement.…”

“…Second, light diffraction and wave guiding increase the light path within the active layer. Nanoimprinting of PEDOT:PSS can indeed increase the device efficiency up to 90 % compared to flat devices [97], but because of its sensitivity to high pressure and temperature [98,99], soft mold (e.g., PDMS [97,100,101] and PUA [102]), and low temperature and pressure processes must be employed (Table 1). Only recently Yang et al showed that T-NIL of PEDOT:PSS with hard mold can achieve 15 % efficiency enhancement in spite of thermal degradation when the polymer is dehydrated in dry environment for 24 h [103].…”

In this chapter we review the use of nanoimprint lithography and its derivative soft-lithography techniques for the fabrication of functional photonic crystals. Nanoimprint is a viable, scalable, and cost-effective solution for large area patterning. While initially it relied primarily on pattern transfer from a rigid mold to a thermally softened polymer by embossing, in the last two decades the process evolved rapidly, giving rise to new technologies that allow direct imprint of functional materials such as conjugated polymers, metals, biological matter, and metal oxides. These advancements generated increasing interest in the use of nanoimprint lithography for the fabrication of photonic structures for light management in optoelectronic devices. After describing standard nanoimprint lithography and its derivative soft-lithography methods, we briefly discuss nanoimprint capabilities and prospects in photonic applications. In particular we review recent implementations of imprinted photonic structures for light management in organic light emitting diodes, solar cells, solid state lasers and sensors.
