This chemical is primarily used in the synthesis of advanced materials, particularly in the development of porous organic polymers (POPs) and covalent organic frameworks (COFs). Its multiple aldehyde groups make it a versatile building block for creating highly ordered and stable structures with tailored porosity. These materials are applied in gas storage and separation, such as capturing CO2 or storing hydrogen, due to their high surface area and customizable pore sizes. Additionally, it is utilized in the fabrication of sensors and catalysts, where its structural rigidity and functional groups enhance performance. In the field of optoelectronics, it contributes to the design of organic semiconductors and light-emitting materials, leveraging its conjugated biphenyl core for efficient charge transport.
