Used in the synthesis of organic semiconductors and perovskite materials for optoelectronic devices such as solar cells and light-emitting diodes (LEDs). Acts as a precursor to introduce thiophene-based cations into perovskite structures, enhancing moisture stability and influencing crystal growth. Also employed in surface modification of nanomaterials to improve charge transport properties. Its aromatic sulfur-containing ring aids in tuning energy levels and intermolecular interactions in thin-film electronics.
