PEDOT-PSS的光图案化是期望的，但由于PEDOT的不溶性和在膜中没有生成PSS的替代方案而麻烦。我们合成了能够自催化生成PSS的酸放大剂（AAs）。AA增加了PSS的浓度，具有来自PAG的催化量的酸。此外，我们使用易于分散在有机溶剂中的PEDOT-PEG（PEDOT：聚乙二醇）。通过使用这些AA、PEDOT-PEG和PAG，我们在干法中获得了PEDOT-PSS的结晶。所获得的图案具有高的透明度，以及106级之间的差异，在曝光（半导体）和未曝光（绝缘体）部分的导电性。
Photopatterning of PEDOT–PSS is desired but troublesome due to the insolubility of PEDOT and no alternatives of generating PSS in the film. We synthesized acid amplifiers (AAs) that can generate PSS autocatalytically. The AAs increase the concentration of PSS, with a catalytic amount of acids from PAGs. Furthermore, we used PEDOT–PEGs (PEDOT:polyethylene glycols) that disperse easily in organic solvents. By using these AAs, PEDOT–PEGs, and PAGs, we obtained photopatterns of PEDOT–PSS in a dry process. The obtained patterns had high transparency as well as a 106order of difference in conductivity between the exposed (semiconductor) and unexposed (insulator) parts.
