| Outline of Final Research Achievements |
We developed novel host materials aiming for the harvesting of the triplet excitons into emission by suppression of the nonradiative decay. We demonstrate that long-lived emission from triplet excitons can be achieved even at high temperature by encapsulating organic emitter in metal organic frameworks (MOFs). Moreover, we demonstrate an organic light-emitting diode (OLED) containing a long-lived phosphorescence emitter that displays electroluminescence with long transient decay after it is turned off. To achieve LLP from an emitter layer, we developed the host molecule 3-(N-carbazolyl)-androst-2-ene (CzSte), which can minimize the nonradiative decay of guest emitter molecules.
