Abstract
Dipolar compounds for use in simplified, single-layer organic light-emitting devices (OLEDs) containing a dibenzothiophene S,S-dioxide core and two peripheral diarylamines are synthesized. These materials exhibit bipolar carrier-transport properties, and efficient single-layer electroluminescent devices (see Figure; ITO: indium tin oxide) using these materials are demonstrated. These compounds may lead to devices with performances comparable to multilayer ones at lower costs.
