Used primarily in organic synthesis and materials science, this compound serves as a building block for constructing complex polycyclic aromatic systems. Its halogenated structure makes it suitable for cross-coupling reactions, such as Suzuki or Ullmann reactions, enabling the development of conjugated organic semiconductors and fluorescent dyes. It is also employed in the synthesis of functional dyes and photoactive compounds due to the presence of the phenanthrenequinone core, which can participate in redox processes and light-induced electron transfer. Additionally, its rigid aromatic framework supports applications in the design of organic electronic materials, including those used in OLEDs and molecular sensors. In photochemical and photophysical research, the extended aromatic structure and multiple halogens enable specific light absorption and function as a photosensitizer for reactive oxygen species (ROS) generation, facilitating studies on energy and electron transfer in molecular systems, with potential in optoelectronics and light-sensitive chemical sensors.
