Cover Story: An extremely interesting derivative of fluorene, which has been garnering increasing interest in recent years, is dibenzofulvene (DBF) and its further structural modifications. In this article, an attempt was made to explain the influence of N-donor substituents on selected physicochemical properties of dibenzofulvene derivatives (A-1–A-6). Moreover, these properties were compared to the results obtained for unsubstituted fluorene. The studies conducted showed that small modifications of the fluorene structure towards dibenzofulvene derivatives significantly change the absorption and emission properties of the final compounds. Importantly, the abovementioned structural modifications strongly affect the electrochemical properties and significantly reduce the energy gap. View this paper
