2-(3-Octadecyloxy-2,2-bis-octadecyloxymethyl-propoxy)-9-(4-chlorophenyl)-9-fluorenol (66 mg, 56 μmol) was dissolved in chloroform (1 ml), acetyl bromide (41 μl, 0.55 mmol) was added dropwise thereto and the mixture was stirred for 2 hours. After completion of the reaction, the solvent was evaporated, and the residue was crystallized from acetonitrile (1 ml) to give 2-(3-octadecyloxy-2,2-bis-octadecyloxymethyl-propoxy)-9-(4-chlorophenyl)-9-bromofluorene (55 mg, 44 μmol, 79%). δ=0.88 (9H, t, J=6.9 Hz, OC18H37 C18-H) 1.1-1.6 (96H, br, OC18H37 C2-17-H) 3.37 (6H, t, OC18H37 C1-H) 3.47 (6H, s, —CH2—OC18H37) 3.97 (2H, m, fl-OCH2—) 6.93 (1H, d, fl C3-H) 6.95 (1H, s, fl C1-H) 7.13-7.57 (9H, m, Ph C2,3,5,6-H, fl C4,5,6,7,8-H)
