PHENYLENEDIAMINE COMPOUNDS FOR PHOSPHORESCENT DIAZABOROLE METAL COMPLEXES

摘要

PROBLEM TO BE SOLVED: To provide phenylenediamine compounds that may facilitate tunability and provide stability in diazaborole metal complexes, or at least provide alternative or improved phosphorescent compounds and emission materials for OLEDs.SOLUTION: The present disclosure generally relates to phenylenediamine compounds, which may be used as precursors in preparing diazaborole compounds and phosphorescent diazaborole metal complexes. The present disclosure also relates to diazaborole compounds, diazaborole metal complexes, and electroluminescent emission materials and electronic devices thereof. The present disclosure further relates to processes for preparing the phenylenediamine compounds and diazaborole metal complexes.
