A difluorinated benzonitrile building block

Used as electron acceptors in OLEDs and catalysts in organometallic chemistry

3,5-Difluorobenzonitrile (CAS number 64248-63-1) is a benzonitrile derivatives with two fluorine substituents at the meta-positions. 3,5-Difluorobenzonitrile is applied as an electron acceptor unit in axially chiral excimers/exciplexes showing cyan luminescence. The exciplexes also display thermally activated delayed fluorescence (TADF), which are promising for OLEDs. The chromophore size of 3,5-difluorobenzonitrole can be expended with carbazole derivatives through nucleophilic aromatic substitution. The synthesized 3,5-difluorobenzonitrole-carbazol emitters have photoluminescence quantum yield (PLQY) of 29% and external quantum efficiency (EQE) of 5.3%.

3,5-Difluorobenzonitrile has also found its use in organometallic chemistry. 3,5-Difluorobenzonitrile assists the conversion of catalytically inactive (phosphine)2Ni to (phosphine)Ni(alkene), a desired catalyst intermediate in cross coupling-reactions.
