3,6-bis(4-(octyloxy)phenyl)-carbazole (4.2 g, 7.29 mmol), 1-bromooctane (4.25 g, 22.0 mmol) and tetrabutylammoniumhydrogensulphate (0.64 g, 1.88 mmol) was dissolved in toluene and mixed with NaOH 50% aqueous solution (5.5 ml). The reaction was quenched after 4 h, extracted three times with ether, and the combined organic phases was washed with water, evaporated, and purified using column chromatography with a 5/2 petroleum ether/toluene mixture as mobile phase. The product was obtained as colourless oil which crystallized to give 9-octyl-3,6-bis(4-(octyloxy)phenyl)-carbazole (1.34 g, 1.95 mmol) as white crystals. 1H NMR(C2D2Cl4, δ): 0.7-0.9 (m, 9H), 1.15-1.45 (m, 30H), 1.758 (m, 4H), 1.848 (m, 2H), 3.957 (t, 4H), 4.251 (t, 2H), 6.951 (d, 4H), 7.389 (d, 2H), 7.61 (m, 6H) 8.23 (s, 2H) MS MALDI-TOF (m/z): 687.461
