Beschreibung
2-bromo-9, 9-diphenylfluorene (2-Bromo-9,9-diphenyl-9H-fluorene) appears as an off-white solid. It belongs to the fluorene group compound. It is a kind of OLED (organic light-emitting diodes) intermediate. It can be used for the production of 9, 9-diphenylfluorene-capped oligothiophenes which can be used as active materials such as filed-effect transistors and light-emitting diodes.
Chemische Eigenschaften
off-white powder
Synthese
10 g (30 mmol) of 2-bromo-9-phenyl-9H-fluoren-9-ol was dissolved in 60
ml of benzene, and 2.4 ml (45 mmol) of concentrated sulfuric acid
diluted with a small amount of benzene was added to the solution. The
mixture was stirred for 5 hours at 80?? C, and after evaporating the
benzene, 1 N sodium hydroxide solution was added to the remaining
solution to a pH of around 7. The mixture was extracted 3 times with
ethyl acetate (40 ml). The collected organic layer was dried with
magnesium sulfate, and the residue obtained by evaporating the solvent
was separated and purified by silica gel column chromatography. 6 g of 2-Bromo-9,9-diphenyl-9H-fluorene (yield: 50%).
