3,6-Dibromocarbazole
1. Basic Information
Name: 3,6-Dibromocarbazole
Alias: 3,6-Dibromo-9H-carbazole
CAS No.: 6825-20-3
Molecular Formula: C12H7Br2N
Molecular Weight: 321.00
Category: Optoelectronic material intermediate, OLED monomer raw material, organic semiconductor building block, pharmaceutical heterocyclic reagent
2. Physical and Chemical Properties
Physical Properties
- Appearance: Off-white to light beige crystalline powder
- Odor: Odorless with faint characteristic aromatic heterocycle smell
- Solubility: Soluble in hot toluene, chloroform, THF, DMF and DMSO; slightly soluble in cold ethanol; insoluble in water, petroleum ether and aliphatic alkanes
- Melting Point: 214–218 °C
- Predicted Density: 1.86 g/cm3
- Hygroscopy: Non-hygroscopic under normal sealed storage environment
- Aqueous property: Weakly alkaline nitrogen heterocycle; stable in neutral cold water without spontaneous hydrolysis at room temperature
Chemical Properties
- Molecular structure: Carbazole parent ring with two bromine atoms substituted at C3 and C6 positions; contains reactive N-H bond and two aryl bromide sites suitable for cross-coupling reactions
- Cross-coupling reactivity: Aryl bromide groups undergo Suzuki, Buchwald, Sonogashira and Stille coupling to construct conjugated organic luminescent skeletons
- N-H functionalization: The pyrrolic NH on carbazole can be alkylated, arylated or protected to modify molecular solubility and optoelectronic performance
- Photostability: Moderately light-sensitive; long-term intense UV irradiation leads to slight discoloration and trace de-bromination impurities
- Thermal stability: Stable below 200 °C; heating above melting point triggers thermal decomposition and releases irritant bromine-containing volatile substances
- Compatibility: Compatible with anhydrous high-boiling aromatic and polar aprotic solvents; incompatible with strong oxidants and concentrated strong alkali under heating
