Atmofair 1,2,4,5-Tetrakis(2-phenylviny)benzene (CAS 25634-86-0)

1,2,4,5-Tetrakis(2-phenylvinyl)benzene (CAS 25634-86-0) has a molecular formula of C₄₀H₃₂ and a molecular weight of 512.68 g/mol, with four phenylethenyl (-CH=CH-C₆H₅) groups at the 1,2,4,5 positions of the central benzene ring. As a symmetric π-conjugated aromatic compound, it is widely used in optoelectronic materials (e.g., OLEDs, organic solar cells) for its excellent light-emitting and charge-transport properties. It should be stored sealed under cool, dry, dark conditions to prevent oxidation, maintaining its structural and electronic integrity for advanced material applications.
