Versuchsvorschrift

To a mixture of 5.2 g (16 mmol) 2,7-dibromofluorene in 300 mL THF was added 1.3 g (41 mmol) sodium hydride (75%) in several portions. A mixture of 15 g (39 mol) N-(10-bromodecyl)-carbazole (8) in 100 mL THF was added dropwisely at 70° C. and the mixture was refluxed for 48 h. After cooling, the solid was filtered and the filtrate was concentrated and dilute with water and extracted with CH2Cl2. The organic layer was collected and washed with brine and dried with anhydrous MgSO4. The crude product was further purified by silica column chromography to give 5.1 g (yield 34%, mp 94˜96° C.) title product. 1H NMR (CDCl3), δ (ppm): 8.10 (4H, d), 7.38˜7.48 (14H, m), 7.23 (4H, t), 4.27 (4H, t), 0.88˜1.86 (36H, m). Anal. Calcd: C, 73.22; H, 6.68; N, 3.00. Found: C, 72.58; H, 6.59; N, 2.73.
