9-phenyl-9H,9'H-3,3'-bicarbazole (CAS 1060735-14-9)

Application and positioning

9-Phenyl-3,3'-bicarbazole links two carbazoles at the 3,3' positions with one nitrogen blocked, so the molecule keeps a single free NH for polymerisation or coupling. The 3,3' linkage keeps the rings conjugated but twisted, which is what gives bicarbazoles their high triplet energy and film stability. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the documentation your market requires.

Quality and documentation

• Batch-specific Certificate of Analysis with HPLC or GC purity and a full impurity profile
• Trace metal report (Pd, Fe, Cu) on request — residual catalyst is what limits OLED device lifetime
• Water content by Karl Fischer and residual solvent data for solution-processed grades
• SDS in the language of your market, with GHS classification for the destination
• Pre-shipment sample for laboratory approval on first orders

Packaging and handling

• 1 kg, 5 kg and 25 kg fibre drums with inner PE liner; amber glass bottles for gram to kilogram quantities on request
• Sealed and protected from light — carbazoles discolour under prolonged UV exposure
• Store at ambient temperature in a dry, dark warehouse, away from strong oxidising agents
