Red Fluorescent Emitting Materials Based on Di-tert-Butyl Chromene Derivatives for Organic Light-Emitting Diodes

초록

In this paper are described two di-tert-butyl chromene-containing red fluorescent materials (Red 1 and Red 2). To explore the electroluminescence properties of these materials, multilayered OLEDs using these materials as dopants in a Alq(3) host were fabricated. In particular, a device using Red 2 as the dopant material showed maximum luminous efficiencies and power efficiencies of 1.14 cd/A and 0.58 lm/W, respectively. The CIEx,y coordinates of this device were (0.67, 0.32) at 7.0 V.
