Used in organic semiconductor materials due to its extended aromatic structure and rigid planar framework. Shows potential in photovoltaic cells and organic light-emitting diodes (OLEDs) as a fluorescence emitter or host matrix. Its sulfur-containing heterocycle enhances electron transport properties. Also investigated in dye-sensitized solar cells for improved light absorption and charge separation. Suitable for optoelectronic applications requiring thermal stability and tunable band gaps.
