Used in the synthesis of advanced organic materials, particularly in the development of porous organic polymers (POPs) and covalent organic frameworks (COFs). Its multiple aldehyde groups enable the formation of robust, highly ordered structures with applications in gas storage, separation, and catalysis. It is also employed in the creation of fluorescent sensors and optoelectronic devices due to its ability to form conjugated systems. Additionally, it serves as a key building block in the design of drug delivery systems and molecular recognition platforms.
