9,9-Dihexyl-2,7-dibromofluorene Chemical Properties,Usage,Production

Chemical Properties

White to brown crystal or powder

Uses

It finds its application as an intermediate for polymeric light-emitting diodes and as an OLED material because of their pure blue emission and efficient electroluminescence coupled with a high charge-carrier mobility and good process ability.

General Description

Intermediate for polymeric light-emitting diodes.

Synthesis

111-25-1

16433-88-8

189367-54-2

General procedure for the synthesis of 9,9-dihexyl-2,7-dibromofluorene from 2,7-dibromofluorene and 1-bromohexane: 2,7-dibromofluorene (1.5 g), and triethylbenzylammonium chloride (0.009 g) were suspended in 30 mL of dimethylsulfoxide in a triple-necked flask. 1.5 mL of 50 wt% aqueous sodium hydroxide solution was slowly added dropwise and the reaction was carried out for 30 min followed by the addition of 1.59 g of 1-bromohexane dropwise. The reaction mixture was stirred at room temperature for 3 h. After completion of the reaction, it was extracted with ether. The organic phase was sequentially washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure and the resulting crude product was recrystallized from aqueous ethanol to give orange needle-like crystals of 2,7-dibromo-9,9-dihexylfluorene (1.96 g) in 86% yield.
