Used as a key building block in the synthesis of coordination polymers and metal-organic frameworks (MOFs), particularly due to its rigid, planar structure and ability to act as a bridging ligand. Its carboxylic acid groups readily coordinate with metal ions, enabling the construction of porous materials with potential applications in gas storage, separation, and catalysis.

Also employed in the development of fluorescent materials and sensors, as the stilbene core exhibits strong photoluminescence when incorporated into solid-state structures.

Additionally, derivatives are explored in textile and polymer industries for UV absorption and optical brightening effects, such as in laundry products, fabric softeners, and bleaches to maintain fabric brightness after multiple washes, and in specialty polymers like films requiring fluorescence.
