Used primarily in organic electronics, this chemical serves as a semiconducting polymer in the active layer of organic light-emitting diodes (OLEDs) and organic photovoltaic cells (OPVs). Its conjugated backbone allows efficient charge transport and tunable light emission, making it suitable for flexible displays and low-cost solar cells. It is also employed in research settings for developing sensors and field-effect transistors due to its solution-processability and optoelectronic properties.
