Pyridine-carbonitrile compound and electroluminescent device including the same

The present invention provides 11-arylcinnolino[2,3-f]phenanthridinium salt compounds and method for producing the same by highly regioselective synthesis of 11-phenylimino[2,3-f]phenanthridin-9-ium salts from 2-azobiaryls and alkenes under catalysis of palladium, through double oxidative C—H coupling of alkenes, to give the polycyclic cinnolinophenanthridinium salts in moderate yields. The reaction mechanism involves ortho C—H olefination of 2-azobiaryls by alkenes, intramolecular aza-Michael addition, β-hydride elimination, electrophilic palladation followed by intramolecular C—H activation and reductive elimination. The prepared quaternary ammonium salts are candidate materials for solution-processable OLED and bioimaging materials.
