Used as an intermediate in organic synthesis, particularly in the preparation of functional materials for optoelectronic devices. Commonly employed in the development of organic light-emitting diodes (OLEDs) due to its ability to enhance electron transport and thermal stability when incorporated into emissive or charge-transport layers. Also utilized in the synthesis of carbazole-based polymers and small molecules for photovoltaic cells and field-effect transistors. The trimethylsilyl group acts as a protective moiety and can improve solubility and processability during device fabrication.
