Organic semiconductors (OSC) have been widely used in electronic devices spanning light- harvesting and light-emitting devices and transistors. Research typically deals with the generation and transport of electronic charge carriers that form the basis of the active research field of organic electronics. More recently, new research directions have emerged, especially the study of ionic transport and mixed coupled ionic-electronic charge transport in OSCs. This field has created new opportunities for organic materials in electrochemical and photo-electrochemical devices. The symposium aims to answer fundamental questions on how ion/electron pairs move within organic materials, the surface chemistries involved in such transport, and physical properties that support ion transport in the bulk as uncovered in recent experimental and theoretical works. Additionally, the symposium will provide an overview of new devices and technologies, including neuromorphic computing, energy storage and conversion technologies, photocatalysis, and electrochromic displays. The symposium further aims to bring together researchers from various backgrounds in an open-minded research atmosphere to learn from each other, discuss new findings and form new collaborations to push forward the field of organic mixed-ionic electronic conductors (OMIECs). The organizers are looking forward to receiving contributions from material chemists as well as experimentalists and theorists, exploring the unique properties of OMIECs.

Darren J. Lipomi earned his bachelor’s degree in chemistry with a minor in physics as a Beckman Scholar at Boston University in 2005. He earned his PhD in chemistry at Harvard University in 2010, with Prof. George M. Whitesides, where he was supported by a fellowship from the ACS Organic Division. From 2010 – 2012, he was an Intelligence Community Postdoctoral Fellow in the laboratory of Prof. Zhenan Bao at Stanford University. He is now a Professor in the Department of NanoEngineering and Program in Chemical Engineering at the University of California, San Diego. His research interests include the chemistry of organic materials, especially the mechanical properties of pi-conjugated polymers for flexible solar cells, biomechanical sensors, and phenomena that occur at the intersection of materials chemistry with human perception and cognition. He is the recipient of the NSF BRIGE award, the AFOSR Young Investigator Program award, the NIH Director’s New Innovator Award, and the Presidential Early Career Award for Scientists and Engineers. He hosts a podcast, “Molecular Podcasting with Darren Lipomi” and associated YouTube channel (Darren_Lipomi) that together have >10,000 subscribers. These venues serve as a resource to students, postdocs, and other early-career researchers. His research website is lipomigroup.org.
