CAS.393841-81-1 2′-Bromo-2,7-di-tert-butyl-9,9′-spirobi[fluorene]

The spirobifluorene structure is a highly conjugated rigid aromatic ring that provides excellent charge transfer properties. The high efficiency of charge transfer is crucial for improving the luminous efficiency of OLED devices. The spirobifluorene structure of this compound helps to enhance charge transfer, ensuring efficient recombination of electrons and holes in the luminescent layer, thereby improving luminescence efficiency and brightness. In addition, the spirobifluorene structure not only provides excellent charge transfer ability, but also has good optical properties, making it a precursor for luminescent materials. Through further chemical modification, 2-bromo-2,7-di-tert-butyl-9,9-spirobifluorene can be used to synthesize OLED materials with specific emission wavelengths, especially exhibiting potential in blue or white light emitting devices.
