Precise control of CT states pioneering advanced organic devices

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, we will mention the improvement of the efficiency and durability of organic devices, clarify the correlation between individual molecular design and macroscopic device characteristics, and provide an overview of the future development of organic devices.
