  • Arylamine-substituted divinyl fluorenes and their use for electrophotographic applications, and for OLEDs (organic light emitting devices)
    Patent number: 8629300
    Abstract: The invention relates to arylamine-substituted divinyl fluorenes. The invention is based on the object of providing photoconductors having good durability, high sensitivity, and low residual potential. The task is to detect new perforated conductors, which can be used in electrophotography, for copying, and in the OLED field. The task is solved by the production of the title compounds, particularly of the formula (11).
