Description

9H-Carbazole, 9-(1-Octylnonyl)-3,6-Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)- is a high-purity, functionalized carbazole derivative containing pinacol boronate ester groups at the 3- and 6- positions. This compound matters as a critical advanced organic intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the precise construction of complex organic electronic materials. It is essential for R&D and production teams in the organic semiconductor, OLED (Organic Light-Emitting Diode), and photovoltaic materials sectors who require reliable, high-quality building blocks for next-generation optoelectronic devices.

Application

• Key Monomer for Conjugated Polymers: Serves as a fundamental building block in the synthesis of donor-acceptor (D-A) type polymers for organic photovoltaics (OPVs) and field-effect transistors (OFETs).
• OLED Emitter and Host Material Precursor: Used to create carbazole-based small molecules and dendrimers that function as deep-blue emitters, hole-transport layers, or host materials in OLED displays and lighting.
• Suzuki Cross-Coupling Reactions: The pinacol boronate ester groups make it an ideal partner for palladium-catalyzed coupling with aryl halides, allowing for efficient, scalable synthesis of extended π-conjugated systems.
• Organic Electronic Material Research: A vital reagent for academic and industrial R&D focused on developing new materials with tailored HOMO/LUMO energy levels, charge mobility, and thermal stability.
• Liquid Crystal and Sensor Material Synthesis: Employed in the preparation of functional discotic liquid crystals or chemical sensors where the carbazole core provides photophysical and electrochemical activity.

Quality Control

Every batch of our 9H-Carbazole derivative is synthesized and purified under controlled conditions to meet the stringent requirements of advanced materials research. We employ rigorous analytical techniques including HPLC, NMR (¹H and ¹³C), and mass spectrometry to verify chemical identity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and residual solvent levels is provided with each shipment to ensure traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Allow the sealed container to reach room temperature before opening to prevent condensation and moisture ingress.
