Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has been extensively used in various fields including organic light emitting diodes, actuators, sensors, and solar cells. Patterning of this conducting polymer is of practical importance, and many efforts have been devoted to fabricating PEDOT:PSS patterns on solid substrates. However, the majority of strategies developed for PEDOT:PSS patterning suffer from either poor conductivity or complicated protocols. Herein, we report a very efficient method for the fabrication of highly conductive PEDOT:PSS patterns. We were able to fabricate a highly conductive PEDOT:PSS film (∼2000 S/cm) on a flexible substrate by using the photo-crosslinkable and water soluble diacetylene diol hexa-2,4-diyne-1,6-diol (DADOL-1). Application of photolithographic technology to a thin film of PEDOT:PSS-DADOL composite allowed the generation of micron-sized PEDOT:PSS patterns. The simple photomasked UV irradiation/washing with water strategy developed in this study should be an important addition for meeting the increasing demand for highly conducting polymer patterns.

聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）已广泛用于各种领域，包括有机发光二极管，致动器，传感器和太阳能电池。对该导电聚合物进行图案化具有实际重要性，并且已经进行了许多努力来在固态基板上制造PEDOT：PSS图案。但是，为PEDOT：PSS图案开发的大多数策略都存在导电性差或协议复杂的问题。在此，我们报告了一种用于制造高导电性PEDOT：PSS图案的非常有效的方法。通过使用可光交联的水溶性二乙炔二醇hexa-2,4-diyne-1,6-diol（DADOL- 1）。光刻技术在PEDOT薄膜中的应用：PSS-DADOL复合材料允许生成微米尺寸的PEDOT：PSS模式。在这项研究中开发的简单的光掩膜紫外线照射/水冲洗策略应该是满足对高导电性聚合物图案不断增长的需求的重要补充。
