Report Abstract: Flexible electronics has become a focal point across multiple disciplines, including materials science, chemistry, and electronics. Flexible electronic products—such as flexible displays, wearable devices, and electronic skin—are poised to exert profound impacts on human production and daily life. After years of development, light-emitting technologies based on organic small molecules have reached a high level of maturity and have been successfully commercialized, finding wide application in mobile phones, televisions, and other devices; meanwhile, flexible electronic technologies based on photoelectric functional polymers are currently in a critical stage of development. The development of novel materials and the advancement of new technologies have endowed this field with broad prospects for growth. Our research efforts are focused on the design, fabrication, and functional tuning of novel high-performance printable organic polymer-based photoelectric materials, interfacial materials, and electrode materials, with the aim of overcoming key technical bottlenecks in the controllable fabrication of high-performance, large-area flexible printed electronic devices.
