The Chemistry of (9-phenylcarbazol-2-yl)boronic Acid

(9-phenylcarbazol-2-yl)boronic acid (CAS No: 1001911-63-2) is an organic compound characterized by a carbazole core substituted with a phenyl group at the nitrogen atom and a boronic acid group at the 2-position. Its molecular formula is C18H14BNO2, with a molecular weight of 287.12. Typically presented as an off-white powder with a high purity level (≥98.0%), this compound is stable under recommended storage conditions and is packaged in quantities such as 25 kg drums, with options for custom packaging to suit specific industrial needs.

The significance of the boronic acid functional group lies in its reactivity, particularly in palladium-catalyzed cross-coupling reactions like the Suzuki-Miyaura coupling. This reaction allows for the efficient formation of new carbon-carbon bonds, enabling chemists to link this carbazole building block with other molecular fragments to construct the complex organic semiconductor molecules required for OLEDs. The carbazole unit itself is known for its excellent charge-transporting capabilities, thermal stability, and relatively high triplet energy, making it an ideal component for various layers within an OLED device.

Applications in OLED Technology

The primary application of (9-phenylcarbazol-2-yl)boronic acid is as a precursor for synthesizing molecules used in OLED devices. These applications include:

  • Blue Emitter Host Materials: The inherent high triplet energy of carbazole derivatives makes them excellent candidates for host materials in blue phosphorescent OLEDs, which are notoriously difficult to develop. The phenyl substituent can further tune the electronic and morphological properties.
  • Hole Transport Materials (HTMs): The carbazole core is a well-established moiety for hole transport, contributing to efficient charge injection and movement across the device, thereby improving overall efficiency and device lifetime.
  • Thermally Activated Delayed Fluorescence (TADF) Emitters: Advanced molecular designs incorporating carbazole units are being explored for TADF applications, offering a path to highly efficient emitters without the need for precious metals.

Researchers and formulators seeking to buy these advanced materials often look for reliable manufacturers in China that can supply (9-phenylcarbazol-2-yl)boronic acid with consistent high purity. This ensures predictable reaction outcomes and reliable performance in the final OLED products.
