1,3-Bis((trimethylsilyl)ethynyl)benzene（Cat No.:L020517）is an aromatic compound with two trimethylsilyl (TMS) protected ethynyl groups attached at the 1 and 3-positions on a benzene ring. The TMS groups provide stability to the ethynyl groups, which can participate in cross-coupling reactions like Sonogashira or Suzuki couplings once deprotected. This compound is commonly used as a precursor in the synthesis of conjugated organic materials, particularly for organic electronics, light-emitting diodes, and conductive polymers. The ethynyl functionality allows for the formation of extended π-systems, while the TMS groups enhance solubility and prevent unwanted side reactions.
