Uses

2-Bromo-9,9-dimethylfluorene can be used as a conducting polymer in the fabrication of a variety of devices which include photoelectronic devices, organic light emitting diodes (OLEDs) and organic solar cells (OSCs).

General Description

2-Bromo-9,9-dimethylfluorene is a fluorene derivative which shows π-electron conjugation. It has a high fluorescent and high electron delocalization. It can be used as a non-linear optical (NLO) material. It can be synthesized by using 2-bromofluorene and iodomethane as the major reactants. It can be majorly used in organic electronic based applications.

Synthesis

28320-31-2

General procedure for the synthesis of 9,9-dimethyl-2-bromofluorene from 9,9-dimethylfluorene: 1) Add 5 g of 9,9-dimethylfluorene, 0.35 g of benzyltriethylammonium bromide, and 0.77 g of sodium bromate to a 100 mL round bottom flask; 2) In another 100 mL round-bottomed flask fitted with a thermometer and a constant-pressure dropping funnel, 34.5 mL of water and 23 mL of methylene chloride were added through the constant-pressure dropping funnel; 3) Stir the liquid in the mixed flask at atmospheric pressure until the solid is completely dissolved, controlling the reaction temperature to 10 °C; 4) Slowly add 7.5 mL of 40% by weight hydrobromic acid dropwise to the reaction mixture of step 3 via a constant pressure dropping funnel, and after completion of the dropwise addition, continue to stir the reaction for 1.5 hours at room temperature; 5) The reaction solution from step 4 was allowed to stand and layered to separate the aqueous phase from the organic phase; 6) Perform one dichloromethane extraction of the aqueous phase, the extract is combined with the organic phase of step 5, and the combined organic phase is washed three times with distilled water; 7) The organic phase of step 6 was dried with anhydrous sodium sulfate, filtered and concentrated, and the resulting product was recrystallized with ethanol and dried under vacuum at 60 °C. The final yield of 9,9-dimethyl-2-bromofluorene was obtained as 73%, and the HPLC detection showed that the purity of the product was 90%, and the product was white solid powder.
