Used in organic light-emitting diodes (OLEDs) as an emissive layer material due to its tunable fluorescence and good charge transport properties. Its amino-functionalized side chains enable efficient electron injection, making it suitable for use in light-emitting electrochemical cells (LECs). Commonly applied in prototype displays and lighting devices where solution-processable semiconducting polymers are required. Also explored in biosensing and imaging applications because of its bright blue emission and ionic conductivity in thin films.
