Versuchsvorschrift

To 11-(2-ethylhexyl)-11H-benzo[a]carbazole (1.65 g; 5.00 mmol) in CH2Cl2 (15 mL) are added 2,4,6-trimethylbenzoyl chloride (0.92 g; 5.11 mmol) and AlCl3 (0.70 g; 5.25 mmol) at 0° C. After stirring at room temperature for 1 hour, AlCl3 (0.70 g; 5.30 mmol) is added at 0° C. and adipoyl chloride (0.43 g; 2.33 mmol) is added dropwise, and then the mixture is stirred at room temperature overnight. The reaction mixture is poured into ice-water, and the crude product is extracted twice with CH2Cl2. The combined organic layer is washed with water and brine, dried over MgSO4, and concentrated to give a green solid. The crude product is purified by column chromatography on silica gel eluting with a mixed solvent of CH2Cl2 and n-hexane (1:1) to give a beige solid (0.85 g; 34.4%). The structure is confirmed by 1H-NMR spectrum (CDCl3). δ [ppm]: 0.82 (t, 6H), 0.89 (t, 6H), 1.17-1.42 (m, 16H), 1.93 (br, 4H), 2.21 (s, 12H), 2.26 (m, 2H), 2.40 (s, 6H), 3.18 (br, 4H), 4.69 (m, 4H), 6.97 (s, 4H), 7.54 (d, 2H), 7.69-7.78 (m, 4H), 8.08 (s, 2H), 8.39 (s, 2H), 8.61 (br, 4H), 9.53 (d, 2H).
