Abstract:Pure aromatic hydrocarbon materials (PHC) represent a new generation of host materials for phosphorescent OLEDs (PhOLEDs), free of heteroatoms. They reduce the molecular complexity, can be easily synthesized and are an important direction towards robust devices. As heteroatoms can be involved in bonds dissociations in operating OLEDs through exciton induced degradation process, developing novel PHCs appear particularly relevant for the future of this technology. In the present work, we report a series of exten… Show more
