Used in organic electronics as a building block for conjugated polymers and small molecules in organic light-emitting diodes (OLEDs). Its rigid, planar structure and multiple ethynyl groups enhance π-conjugation and facilitate charge transport, making it suitable for blue-emitting materials. Also employed in the synthesis of covalent organic frameworks (COFs) for optoelectronic and sensing applications due to its ability to form extended networks through alkyne coupling reactions. Shows potential in photovoltaic devices as a donor material in organic solar cells.
