CAS.2259716-83-9 2-bromo-7-chlorosipro[fluorene-9,9′-xanthene]

The structure of spirofluorene and oxanthracene forms a rigid and highly conjugated molecular framework, which can provide excellent charge transfer performance. In OLED devices, efficient charge transfer is crucial for ensuring effective recombination of electrons and holes in the emissive layer. This compound enhances the luminescence efficiency and overall performance of OLED devices by enhancing charge transfer. In addition to its application in OLED, 2-bromo-7-chlorospiro [fluorene-9,9 ‘- oxanthracene] can also be used in other optoelectronic fields, such as organic photovoltaics (OPV) and organic photoconductors (OPC). Its excellent charge transfer performance and reactivity make it an ideal candidate for efficient optoelectronic materials.
