2,7-Dibromo-9-octyl-9H-carbazole(CAS: 726169-75-1)

2,7-Dibromo-9-octyl-9H-carbazole is a solid at room temperature with a crystalline form. Its molecular weight is approximately 385.27 g/mol. This compound has low solubility in water but good solubility in organic solvents like dichloromethane and toluene. It exhibits limited reactivity under standard conditions, making it stable for most applications. However, it should be handled with caution due to its bromine content.

2,7-Dibromo-9-octyl-9H-carbazole can be synthesized via a Brönsted acid-mediated Friedel-Crafts alkylation reaction. The octyl group is introduced to 9-carbazole using bromine and a suitable catalyst. The reaction is typically conducted in a non-polar solvent, and the yield can be increased by using a Lewis acid catalyst. The product is purified by recrystallization or column chromatography.

2,7-Dibromo-9-octyl-9H-carbazole is used in the semiconductor industry for the fabrication of organic light-emitting diodes (OLEDs). It also finds applications in the development of organic photovoltaic materials and as a dopant in electronic devices. Additionally, it is used in the polymer industry for the synthesis of functional polymers and in the pharmaceutical sector for the development of certain drug molecules.

When handling 2,7-Dibromo-9-octyl-9H-carbazole, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood due to the potential for bromine vapor release. Spills should be handled by containment and appropriate disposal methods, following the Safety Data Sheet (SDS) guidelines. Storage should be in a cool, dry place away from direct sunlight and heat sources.
