Abstract

Two fluorescent benzo[g]quinoline derivatives were synthesized via Friedländer synthesis. Multilayered OLEDs using benzo[g]quinoline derivatives as the emitters showed unexpected emissions by electroplexes. Particularly, a device using 2-(naphthalen-3-yl)-4-phenylbenzo[g]quinoline as an emitting material exhibited efficient emission with a luminous efficiency, a power efficiency, an external quantum efficiency, and CIE coordinates of 3.58 cd/A, 1.11 lm/W, 1.08% at 20 mA/cm², and (0.36, 0.56) at 1,000 cd/m², respectively.
