His work includes publications in prestigious journals such as Advanced Materials, Nature Communications, and Advanced Functional Materials.

Juan Qiao is a researcher in Physical Chemistry with a focus on OLED (Organic Light-Emitting Diodes) technology. His work explores the design and synthesis of small molecules for efficient light emission, including bipolar structures, non-donor-acceptor systems, and materials with high triplet energies. He investigates strategies to enhance the performance of OLEDs through molecular engineering, such as suppressing concentration quenching, improving charge balance, and achieving high power efficiency. His research also extends to perovskite materials for solar cells and light-emitting electrochemical cells, emphasizing stability and efficiency. Qiao's contributions highlight the development of cationic iridium complexes for near-infrared and white light emission, as well as the molecular understanding of chemical stability in organic materials.
