Used as a fluorescent sensor in chemical detection, particularly for metal ions and pH changes due to its strong photoluminescent properties. Its conjugated structure allows for effective electron transfer, making it suitable in optoelectronic applications such as organic light-emitting diodes (OLEDs) and molecular probes in analytical chemistry. Also employed in supramolecular chemistry for designing host-guest systems thanks to its rigid, planar framework that facilitates π-π stacking interactions.
