Special Talk: Advanced Organic Electronics by Controlling Precise Charge Transfer Phenomena (Prof. Chihaya Adachi, Kyushu University, Japan)

Abstract: In the last 10 years, there have been a wide variety of studies on thermally activated delayed fluorescence (TADF)-OLEDs focusing on the unlimited possibilities of molecular design. Further, hyperfluorescence (HF)-OLEDs have been developed since they can realize the compatibility of high efficiency with narrow spectral width, which is ideal for practical display applications. The advanced HF-OLEDs realized high light-emitting performance by engineering host, TADF, and terminal emitter (TE) molecules. Firstly, we mention the comprehensive design principle for the materials and device architectures used in HP-OLEDs by focusing on fast T-S upconversion, negative gap, efficient FRET, GSP, and carrier trapping aimed at high-performance EL. In addition, we underscore the crucial role of CT in organic optoelectronic devices, shedding light on its importance in future organic devices such as organic thermoelectrics).

Bio: Prof. Chihaya Adachi obtained his doctorate in Materials Science and Technology in 1991 from Kyushu University. He held positions as a research chemist and physicist in the Chemical Products R&D Center at Ricoh Co., a research associate at Shinshu University, a research staff at Princeton University, and an associate professor and professor at Chitose Institute of Science and Technology. In 2005, he returned to Kyushu University as a professor and was promoted to a distinguished professor in 2010, and his current posts also include director of Kyushu University’s Center for Organic Photonics and Electronics Research (OPERA) since 2010 and director of the Fukuoka i3 Center for Organic Photonics and Electronics Research since 2013. His research has been concentrated on organic synthesis, device fabrication, and optical and electrical device characterization of organic semiconductors. He has been serving as an editor of “Organic Electronics” (Elsevier) (2007-2019) and CCS Chemistry (2019-). His publications include over 670 research papers. He won Nishina Memorial Award (2017), Nagoya Silver Medal (2019), etc., and was selected as a highly cited researcher (Clarivate) (2018-2023) and Medal with Purple Ribbon (2023).<
