Used as a key intermediate in the synthesis of organic light-emitting diodes (OLEDs), particularly in the development of blue-emitting materials due to its anthracene core, which provides good fluorescence properties. Its carboxylic acid functional group allows for easy attachment to other molecular units or substrates, making it valuable in constructing metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) for optoelectronic applications. Also employed in photovoltaic devices and as a building block in fluorescent sensors, where its extended π-conjugation enhances light absorption and emission efficiency.
