Application

Widely utilized as a model compound for studying photophysical properties of sulfur-containing polycyclic aromatics in optoelectronic materials research. Serves as a key intermediate in the synthesis of organic semiconductors for OLED and OFET applications due to its extended π-system. The rigid planar structure makes it valuable for investigating charge transport mechanisms in thin-film devices. Also employed as a building block for metal-organic frameworks (MOFs) with potential catalytic applications.
