Abstract

The triplet-energy control of polycyclic aromatic hydrocarbons (PAHs) was achieved by heteroatom incorporation. For instance, 4b-aza-12b-boradibenzo[g,p]chrysene showed a much larger ET value than the corresponding PAH, dibenzo[g,p]chrysene, and enable us to built phosphorescent organic light-emitting diodes (PHOLEDs) of high performance. We have also synthesized a variety of heteroatom-incorporated polycyclic aromatics with a large ET value, which improved not only efficiency of PHOLED but also lifetime.
