CAS.2041-19-2 3-Bromo-9H-fluoren-9-one

The fluorenone structure provides a rigid and highly conjugated system that enhances charge transfer capability. In OLED devices, charge transfer efficiency is crucial for luminescence efficiency. The fluorenone structure of this compound facilitates the transfer of electrons or holes in the luminescent layer, ensuring the efficiency of charge recombination and thereby enhancing the overall luminescence performance of the device. In addition, the fluorenone structure has excellent optical properties and can serve as a precursor for luminescent materials. Through further chemical modification, 3-bromo-9H-fluoro-9-one can be used to develop OLED materials with specific emission wavelengths, particularly for the synthesis of blue or white light emitting

devices.
