Used in organic electronics as a building block for synthesizing conjugated polymers and small molecules in organic light-emitting diodes (OLEDs). Its rigid aromatic structure enhances charge transport properties, making it valuable in hole-transport materials and host materials for phosphorescent OLEDs. Also employed in dye-sensitized solar cells and as a precursor for fluorescent dyes and sensors due to its photostability and tunable emission. Active research explores its role in photocatalysis and as a scaffold in medicinal chemistry for developing bioactive compounds.
