Source of materials

To a solution of 5-dibenzosuberenone (0.206 g, 1 mmol) in THF (15 mL), liquid Br2 (0.16 g) was added dropwise at 280 K for 30 min. Then the mixture was stirred at room temperature for 2 h. After the reaction was completed, the solvent was evaporated to give a crude intermediate product. A mixture of intermediate product (0.366 g, 1 mmol), carbazole (0.20 g, 1.2 mmol), potassium carbonate (0.277 g, 2.0 mmol), potassium iodide (0.033 g, 0.2 mmol) and THF (15 mL) was placed in a 50 mL sealed tube under nitrogen. The reaction mixture was stirred at 350 K for 36 h. After completion of the reaction, the mixture was passed through celite filtration, the extract was dried using magnesium sulphate, and then the solvent was removed under reduced pressure. The dried residue was then purified by silica gel column chromatography using an ethyl acetate/n-hexane mixture as eluent to give the desired sky blue colour compound, and recrystallized from methanol to obtain the title compound as colourless block crystals.

Experimental details

Hydrogen atoms were included using riding models implemented in the SHELXL software [3, 4]. Their U iso values were set to 1.2 U eq of the parent atoms. Using Olex2 [2], the structure was solved with the ShelXS [3] structure solution program using Direct Methods and refined with the ShelXL [4] refinement package.

Comment

Over the past three decades, organic light-emitting diodes (OLEDs) have experienced a rapid development [5]. But the development of blue OLEDs materials has been lagging behind due to the high excitation energy and aggregation caused-quenching (ACQ), triplet-triplet annihilation (TTA) and triplet-polar annihilation (TPA) [6]. Here, we designed a heptagonal core skeleton combining the weak electron-withdrawing group of benzophenone and electron-donating group of carbazole (Cz). The title compound has a good balance between rigidity and flexibility and effectively inhibits ACQ and TTA, which makes it a potential blue OLED.

The crystal struture of the title compound is similar with the reported structure [7] of 2-(9,9-dimethylacridin-10(9H-yl)-4-methyl-5H-dibenzo[a,d] [7] annelen-5-one. The three rings in dibenzosuberenone are not in the one plane, and the Cz group is almost perpendicular to the heptagonal skeleton. All the bond lengths and angles of this molecule are in the expected ranges.
