CY2-SE is widely used in the field of organic electronics, particularly in the development of organic light-emitting diodes (OLEDs). Its application is crucial in enhancing the efficiency and stability of light-emitting layers within OLED devices, making it a key component in the production of high-performance displays and lighting systems. Additionally, CY2-SE is employed in research focused on organic photovoltaic (OPV) cells, where it contributes to improving the light absorption and energy conversion efficiency of these solar cells. Its unique properties also make it suitable for use in advanced materials science, particularly in the synthesis of novel organic semiconductors with tailored electronic characteristics.
