Application

This stannane derivative is primarily used in the synthesis of organic semiconductors and conductive polymers, where its extended π-conjugated system enhances charge transport properties. Its dual trimethylstannyl groups serve as versatile handles for Stille cross-coupling reactions, enabling precise construction of complex conjugated architectures for OLEDs or OTFTs. The tetradecyl chains improve solubility in organic solvents while maintaining thin-film processability.
