Used as a key building block in the synthesis of organosilicon-based conjugated polymers and small molecules for organic electronics. Its rigid, planar structure enhances electronic delocalization, making it valuable in organic light-emitting diodes (OLEDs), particularly for blue emitters. Also employed in the development of silicon-bridged ligands for catalysis and in materials for organic photovoltaics (OPVs) due to its thermal stability and tunable electronic properties.
