Used in organic electronics as a building block for conjugated polymers and small molecules in organic semiconductors. Commonly applied in the synthesis of functional materials for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Also serves as a ligand or intermediate in catalytic reactions and pharmaceutical research due to its nitrogen-sulfur heterocyclic structure. Its aromatic and electron-rich nature makes it suitable for sensor development and coordination with metal ions in material science.
