Used in the synthesis of organic electronic materials, particularly in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). It serves as a key building block for creating conjugated polymers and small molecules with high electron mobility and efficient light absorption. Additionally, it is employed in the fabrication of metal-organic frameworks (MOFs) due to its ability to form stable, porous structures. Its aldehyde groups allow for further functionalization, making it versatile in designing advanced materials for optoelectronic applications.
