Used primarily in organic electronics as a key intermediate for synthesizing conjugated polymers via Stille coupling reactions. Its stannane groups enable efficient carbon–carbon bond formation, making it valuable in the fabrication of organic semiconductors for applications such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The long dodecyl side chains enhance solubility in organic solvents, facilitating solution-processing techniques like spin coating or inkjet printing. This improves film uniformity and device performance in large-area electronic devices.
