Transition-Metal-Catalyzed C–C Bond-Forming Reactions via C–H Activation for the Development of Fluorescent Materials with Practical Value

Fluorescent materials of practical value have attracted considerable attention because of their important applications in the fields of bioprobes, chemosensors, organic light-emitting diodes, field-effect transistors, memory devices, security systems, etc. As such, these materials have been improving the quality of our daily life. In the past few decades, chemists and materials scientists have constructed various organic fluorescent molecules using transition-metal-catalyzed C–C bond-forming reactions via C–H activation. This approach provides a unique opportunity for efficient and straightforward access to various organic fluorescent frameworks that cannot be easily constructed by traditional synthetic routes. This Review aims to highlight and help better understand the recent development of transition-metal-catalyzed C–C bond-forming reactions via C–H activation for optimized fluorescent materials of practical value. In addition, some perspectives on the challenges and opportunities in this field will be discussed.
