About

Dean M. DeLongchamp is a leading figure in the field of organic electronics, with a primary focus on understanding and controlling the structure–property relationships of conjugated polymers. His research elegantly bridges materials chemistry and device physics, particularly in the areas of charge transport and mixed ionic-electronic conduction. A landmark contribution is his highly cited 2016 work on "Structural control of mixed ionic and electronic transport in conducting polymers," which has garnered over 898 citations. This study provided critical insights into how the nanoscale morphology of PEDOT:PSS governs its dual conductivity, a key factor for applications in bioelectronics and energy storage. Beyond this, DeLongchamp is renowned for pioneering advanced X-ray and neutron scattering techniques to probe the microstructure of thin-film organic semiconductors, enabling rational design of high-performance materials. His work has been instrumental in advancing the understanding of doping mechanisms and charge carrier mobility, making him a central figure in the push toward practical, solution-processable organic electronic devices.
