1-Ethynyl-4-(phenylethynyl)benzene（Cat No.:L012771）is a conjugated aromatic compound featuring a central benzene ring substituted with an ethynyl group at the 1-position and a phenylethynyl group at the 4-position. This linear, highly π-conjugated structure imparts excellent electronic and optical properties, making it valuable in organic electronic materials such as OLEDs, OFETs, and molecular wires. Its rigid, planar geometry facilitates charge transport and self-assembly in thin films. Additionally, the terminal alkyne group offers a reactive handle for further functionalization via click chemistry or metal-catalyzed coupling, supporting applications in nanotechnology and materials science.
