Used in organic light-emitting diodes (OLEDs) as a fluorescent emitter due to its strong blue luminescence. Also serves as a building block in the synthesis of liquid crystals and photoresponsive materials. Its stilbene core allows for trans-cis isomerization upon UV exposure, making it useful in photochromic applications. Additionally, it has been investigated for use in nonlinear optical devices and as a precursor in the preparation of certain pharmaceutical intermediates.
