Three bifunctional organic materials based on Troger's base (TB) scaffold have been designed, synthesized and their functional utility in OLEDs demonstrated through fabrication of devices. The diarylamino-functionalized TBs, i.e., A-TB, PA-TB and P-TB, are all amorphous with considerably high T(g)s and permit modulation of electroluminescence with variation of one of the N-aryl rings, e.g., anthryl to 10-phenylanthryl to pyrenyl. Subtle structural modifications are found to manifest in rare pure yellow EL emission from PA-TB. (C) 2014 Elsevier B.V. All rights reserved.
