Used primarily in the synthesis of fluorescent dyes and organic semiconductors due to its anthracene backbone, which supports strong π-electron delocalization. Its hydroxyl functional groups allow for easy modification in polymer chains, making it suitable for optoelectronic devices such as OLEDs and sensors. Also serves as a precursor in photochromic materials, where it undergoes reversible light-induced reactions for use in smart windows and data storage systems. Additionally, its derivatives are explored in biomedical imaging for their ability to emit light in the visible range with high quantum yield.
