Used primarily in organic light-emitting diodes (OLEDs) and optoelectronic devices due to its strong blue photoluminescence and electroluminescence. It serves as a semiconductor material in polymer-based LEDs, offering high fluorescence efficiency and good film-forming properties. Its conjugated structure allows for effective charge transport, making it suitable for use in flexible displays, sensors, and as an active layer in polymer solar cells. The hexyl side chains enhance solubility in organic solvents, facilitating solution processing techniques like spin coating and inkjet printing for device fabrication.
