Used as a key intermediate in the synthesis of advanced organic materials, particularly in the development of high-performance liquid crystals and organic semiconductors. Its rigid terphenyl backbone and electron-withdrawing trifluoromethyl groups enhance thermal stability and electronic properties, making it suitable for optoelectronic devices such as OLEDs and OFETs. Also employed in the preparation of specialty polymers and porous organic frameworks for gas separation and catalysis due to its well-defined molecular geometry and functional aldehyde groups that allow for further chemical modification.
