Used as a fluorescent sensor for detecting nitroaromatic explosives like TNT due to its strong emission properties that are quenched in the presence of electron-deficient compounds. Its rigid, conjugated structure makes it highly luminescent, ideal for optoelectronic applications such as organic light-emitting diodes (OLEDs) and molecular wires. Also employed in energy transfer studies and as a building block in supramolecular chemistry for constructing metal-organic frameworks with sensing capabilities.
