Used in organic semiconductor materials due to its extended aromatic core and electron-donating hydroxyl groups. Its rigid, planar structure supports strong π-π stacking, enhancing charge transport in thin-film transistors. Also employed as a fluorescent probe in biochemical imaging, where its dihydropyrene backbone provides high photostability and tunable emission. Serves as a building block in synthesizing conjugated polymers for optoelectronic devices like OLEDs and solar cells.
