• Associated context:

  Over the past decade, fluoren-9-one derivatives have attracted considerable attention due to their presence in natural products1 with a range of biological activities (e.g.,  dengibsin,^1d,g dengibsinin,^1d dendroflorin,^1b cauliphin)^1j and  in pharmaceutically important agents (anticancer, antioxidant, and anti-HIV).² Furthermore, fluorenones, arylated  fluorenones, and benzofluorenones have been incorporated  in oligomers and polymers which have been examined for  potential applications of their optical and electrochemical  properties as organic light-emitting devices³ and liquid  crystals⁴ (Figure 1).
