CAS.1450933-18-2 1-Bromo-9,9′-Spirobi[9H-fluorene]

The spirobifluorene structure is a rigid and highly conjugated molecular structure that provides excellent charge transfer performance. The high efficiency of charge transfer is crucial for improving the luminous efficiency of OLED devices. The rigidity and conjugation of spirobifluorene ensure effective transfer of electrons and holes, which helps to achieve efficient charge recombination and improve the luminescence efficiency of the device. In addition, the conjugated system of spirobifluorene structure and the reactivity of bromine groups can be chemically modified to regulate the electronic structure, thereby affecting the emission wavelength of OLED materials. This flexibility enables the compound to help develop materials with different luminescent colors, suitable for multi-color displays and efficient lighting devices.
