Used as a key intermediate in organic synthesis, particularly in the preparation of extended π-conjugated systems for optoelectronic materials. Its aldehyde functional groups allow for further derivatization, making it valuable in the construction of covalent organic frameworks (COFs) and metal-organic frameworks (MOFs) with tailored porosity and electronic properties. Commonly employed in the development of organic semiconductors, sensors, and fluorescent polymers due to its rigid, multi-armed structure that enhances charge transport and luminescence characteristics. Also finds use in cross-coupling reactions and as a building block for dendritic and star-shaped molecules in materials science research.
