A fluorinated carbazole building block

Used as a synthesis intermediate for bioactive compounds and emitters in application of antimicrobials and OLEDs


2-Fluoro-9H-carbazole (CAS number 391-53-7), derived from carbazole, is a fluorinated aromatic heterocyclic compound with two benzene rings fused by a pyrrole. As the analogue of carbazole, 2-Fluoro-9H-carbazole and its derivatives show antibacterial performance with minimum inhibitory concentration of 25 µg/mL against E. Coli, B. subtilis and S. aureus. 2-Fluoro-9H-carbazole can be easily attached to another halogenated building block via Buchwald-Hartwig amination and copper catalysed alkylation, to enlarge the chromophore size of the molecules.

A fluorinated polyvinylcarbazole synthesised from 2-fluoro-9H-carbazole is exploited as a host material in organic light emitting diodes. It has a higher luminous current efficiency of 24 cd/A than polyvinylcarbazole (17 cd/A), owing to the wider HOMO-LUMO energy gap of the fluorinated polymers.
