Used in organic electronics as a fluorescent building block due to its aggregation-induced emission (AIE) properties. It serves as a key intermediate in synthesizing luminescent materials for OLEDs and sensors. Its twisted molecular structure enhances solid-state emission, making it suitable for optoelectronic devices where high quantum yield in thin films is required. Also employed in the development of chemosensors for detecting metal ions or volatile organic compounds thanks to its strong and responsive fluorescence signal.
