Our laboratory is dedicated to the development of next-generation organic materials, electronic materials, and optoelectronic functional molecules, with a primary focus on the molecular design, synthesis, and functional regulation of polycyclic aromatic hydrocarbons (PAHs). By integrating organic synthesis, materials chemistry, and photophysical analysis, we develop organic π-conjugated systems with unique electronic structures and excited-state behaviors. Through the incorporation of heteroatoms such as boron, nitrogen, oxygen, and sulfur, along with precise control over molecular geometry, stereochemistry, and molecular packing, we establish design principles for high-quality organic optoelectronic materials. Our research topics encompass high-efficiency thermally activated delayed fluorescence (TADF) materials, room-temperature phosphorescence (RTP) molecules, deep-blue and narrowband emitters, organic light-emitting diode (OLED) emissive systems, and organic afterglow materials featuring long-lived excited states and visible persistent luminescence. Beyond elucidating the relationships between excited-state mechanisms and molecular structures, our work extends to applications in display technologies, sensing, information anti-counterfeiting, and emerging photonic functional devices. Through precise molecular-level design and interdisciplinary integration, we aim to advance breakthroughs in both fundamental science and practical applications of novel organic optoelectronic materials.
