title: Zinc complexes exhibiting highly efficient thermally activated delayed fluorescence and their application to organic light-emitting diodes.
abstract: Metal complexes emitting thermally activated delayed fluorescence based on intra-ligand charge transfer and enhanced by metallization were synthesized. Organic light-emitting diodes using a thermally stable zinc complex processed by vacuum vapor deposition achieved an external quantum efficiency of nearly 20%.
