Abstract:
In organic optoelectronic devices, high performance has been achieved through precise molecular design based on various electron-donating and electron-accepting units, which control electrical conduction, exciton generation, charge separation processes, and even spontaneous dipole orientation in thin films. From the aspect of charge transfer phenomena, I will focus on improving the efficiency and durability of TADF-based OLEDs, clarify the correlation between individual molecular design and macroscopic device characteristics, and provide an overview of the future development of organic devices.
