Multifunctional Diarylamine-Substituted Benzo[k]fluoranthene Derivatives as Green Electroluminescent Emitters and Nonlinear Optical Materials
A new series of benzo[k]fluoranthene derivatives incorporating a diarylamine group have been synthesized and characterized. These compounds show high thermal stability with glass transition temperatures in the range of 162-205 °C. Two-layer electroluminescent devices employing them as the hole-transporting layer and light-emitting layer achieved efficient green emission under low driving voltage. A further optimized three-layer device based on one of these compounds, 3-(1-naphthylphenylamino)-7,12-diphenylbenzo[k] fluoranthene (PNDPBF), exhibited a maximum current efficiency of 10.2 cd/A (6.7 lm/W at 4.70 V). Nonlinear optical properties of these molecules were also investigated by measuring their two-photon excited fluorescence. © 2010 American Chemical Society.
