      Organic electronic devices are widely used in our daily life and have become one of the research hotspots in recent years. Professor Myung-Han Yoon gave a brief introduction to the research background of organic electronic devices, expounded the latest research progress and existing problems in this field, and introduced his research work from two aspects. On the one hand, in view of the problems existing in the application of common organic electrolytes such as PMMA and PS in thin-film transistor applications, Professor Myung-Han Yoon proposed the idea of using sulfur-containing polymers as dielectric layers. The sulfur-containing polymer as a dielectric layer exhibits many excellent properties, greatly reducing the leakage current and operating voltage of the device. At the same time, due to the effect of S-S bonds, the device also has the ability of self-healing, which greatly improves the performance of thin film transistors. On the other hand, considering the excellent electrical properties, environmental stability and biocompatibility of PEDOT:PSS Features, Professor Myung-Han Yoon applied it to biosensors. Water-stable electrochemical transistors were fabricated using crystalline PEDOT:PSS films, and the devices exhibited excellent performance, expanding the application of this material in biosensing. Finally, teachers and classmates actively participated in the discussion and exchanged views, which benefited everyone a lot. The report ended successfully with the enthusiastic participation of everyone.
